Version 22.0 [Build 8171]

REST Class

Properties   Methods   Events   Configuration Settings   Errors  

The REST Class can be used to retrieve XML documents from the World Wide Web.

Syntax

ipworks.Rest

Remarks

The REST Class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

The REST Class implements a standard REST client with the added option of SSL security.

The class contains a number of properties that map directly to HTTP request headers. All XML and JSON data received is parsed by the component and provided to the user through properties such as XPath, XElement, XText, etc. which allow traversal of the document structure. The Header event will provide the HTTP headers as returned by the server.

To receive a document, call the Get method with the URL to retrieve specified in the URL parameter. The class will automatically parse the XML or JSON data, depending on the content type that is returned. Call the Delete method to delete a resource specified by the URL parameter.

The Post and Put methods are used to create and update resources. Post is commonly used to both create and update resources, however each service may have its own requirements. To send data to the server set PostData and call the Post or Put method.

To add authorization credentials to an outgoing request, you should specify the User and Password properties. The REST Class supports Basic, Digest, and NTLM authentication through the AuthScheme property.

Accept Property (REST Class)

A list of acceptable MIME types for the request.

Syntax


public String getAccept();


public void setAccept(String accept);

Default Value

""

Remarks

If this property contains a non-empty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.

Authorization Property (REST Class)

The Authorization string to be sent to the server.

Syntax


public String getAuthorization();


public void setAuthorization(String authorization);

Default Value

""

Remarks

If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

AuthScheme Property (REST Class)

The authentication scheme to use when server authorization is required.

Syntax


public int getAuthScheme();


public void setAuthScheme(int authScheme);

Enumerated values:
  public final static int authBasic = 0;

  public final static int authDigest = 1;

  public final static int authProprietary = 2;

  public final static int authNone = 3;

  public final static int authNtlm = 4;

  public final static int authNegotiate = 5;

  public final static int authOAuth = 6;

Default Value

0

Remarks

This property will tell the class which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the class will attempt basic authentication. If AuthScheme is set to authDigest (1), authNtlm (4) or authNegotiate (5), digest, NTLM or Negotiate authentication will be attempted instead.

If AuthScheme is set to authProprietary (2) then the authorization token must be supplied through Authorization property.

If AuthScheme is set to authOAuth (6) then the authorization string must be supplied through Authorization property.

Note that, if you set the Authorization property and AuthScheme is not authProprietary or authOAuth, the AuthScheme will be set automatically to authProprietary (2) by the control.

For security purposes, changing the value of this property will cause the class to clear the values of User, Password and Authorization.

BuildDOM Property (REST Class)

When True, an internal object model of the XML document is created.

Syntax


public boolean isBuildDOM();


public void setBuildDOM(boolean buildDOM);

Default Value

True

Remarks

Set BuildDOM to True when you need to browse the current document through XPath.

Validate is automatically set to True when BuildDOM is set to True.

Connected Property (REST Class)

Shows whether the class is connected.

Syntax


public boolean isConnected();


public void setConnected(boolean connected);

Default Value

False

Remarks

This property is used to determine whether or not the class is connected to the remote host.

Note: It is recommended to use the Connect or Disconnect method instead of setting this property.

This property is not available at design time.

ContentType Property (REST Class)

Content type for posts and puts.

Syntax


public String getContentType();


public void setContentType(String contentType);

Default Value

""

Remarks

If this property contains a non-empty string, a Content-Type HTTP request header is added to the request. The purpose of the header is to show the contents of the data during a Post or Put to the server.

The most common example is posting of HTML form input data. In that case, this property must be set to "application/x-www-form-urlencoded".

This property is not available at design time.

Cookies Property (REST Class)

Collection of cookies.

Syntax


public HTTPCookieList getCookies();


public void setCookies(HTTPCookieList cookies);

Remarks

This property contains a collection of cookies. To add cookies to outgoing HTTP requests, add cookies (of type HTTPCookie) to this collection.

To see cookies that are set by the server, use the SetCookie event, which displays the cookies and their properties as set by the server. Those cookies are also added to Cookies.

MaxHTTPCookies can be used to control the maximum number of cookies saved.

This collection is indexed from 0 to size - 1.

This property is not available at design time.

Firewall Property (REST Class)

A set of properties related to firewall access.

Syntax


public Firewall getFirewall();


public void setFirewall(Firewall firewall);

Remarks

This is a Firewall type property which contains fields describing the firewall through which the class will attempt to connect.

FollowRedirects Property (REST Class)

Determines what happens when the server issues a redirect.

Syntax


public int getFollowRedirects();


public void setFollowRedirects(int followRedirects);

Enumerated values:
  public final static int frNever = 0;

  public final static int frAlways = 1;

  public final static int frSameScheme = 2;

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same, otherwise the class throws an exception.

Note that following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to frAlways (1), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the class throws an exception instead.

From Property (REST Class)

The email address of the HTTP agent (optional).

Syntax


public String getFrom();


public void setFrom(String from);

Default Value

""

Remarks

This property contains the email address of the HTTP agent (optional). If it contains a non-empty string, an HTTP From: header is added to the request. This header generally gives the email address of the requester of the document.

This property is not available at design time.

HTTPMethod Property (REST Class)

The HTTP method used for the request.

Syntax


public String getHTTPMethod();


public void setHTTPMethod(String HTTPMethod);

Default Value

""

Remarks

This property contains the HTTP method used for the request. If an empty string is provided, the HTTPMethod is determined automatically by the method being called. You may change it to a custom value if you require an HTTP method other than what is provided by the class.

This property is not available at design time.

Idle Property (REST Class)

The current status of the class.

Syntax


public boolean isIdle();


Default Value

True

Remarks

Idle will be False if the component is currently busy (communicating and/or waiting for an answer), and True at all other times.

This property is read-only.

IfModifiedSince Property (REST Class)

A date determining the maximum age of the desired document.

Syntax


public String getIfModifiedSince();


public void setIfModifiedSince(String ifModifiedSince);

Default Value

""

Remarks

If this property contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the class throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. An example is Sat, 29 Oct 1994 19:43:31 GMT.

This property is not available at design time.

LocalFile Property (REST Class)

The path to a local file for downloading. If the file exists, it is overwritten.

Syntax


public String getLocalFile();


public void setLocalFile(String localFile);

Default Value

""

Remarks

This property is used when getting a document.

If this property is empty then the received data is provided through TransferredData and the Transfer event.

LocalHost Property (REST Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax


public String getLocalHost();


public void setLocalHost(String localHost);

Default Value

""

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Namespaces Property (REST Class)

A collection of namespaces in the current stack.

Syntax


public XMLNamespaceList getNamespaces();


Remarks

This property contains a collection of XML namespaces, which are standards for providing uniquely named elements and attributes in an XML instance.

The default namespace is found at index 0.

This property is read-only and not available at design time.

OtherHeaders Property (REST Class)

Other headers as determined by the user (optional).

Syntax


public String getOtherHeaders();


public void setOtherHeaders(String otherHeaders);

Default Value

""

Remarks

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the class beyond what is provided.

This property is not available at design time.

ParsedHeaders Property (REST Class)

Collection of headers returned from the last request.

Syntax


public HeaderList getParsedHeaders();


Remarks

This property contains a collection of headers returned from the last request. Whenever headers are returned from the server, the headers are parsed into a collection of headers. Each Header in this collection contains information describing that header.

MaxHeaders can be used to control the maximum number of headers saved.

This collection is indexed from 0 to size - 1.

This property is read-only and not available at design time.

Password Property (REST Class)

A password if authentication is to be used.

Syntax


public String getPassword();


public void setPassword(String password);

Default Value

""

Remarks

This property contains a password if authentication is to be used. If AuthScheme is set to HTTP Basic Authentication, The User and Password are Base64 encoded and the result is put in the Authorization config setting in the form "Basic [encoded-user-password]".

If AuthScheme is set to HTTP Digest Authentication, the User and Password properties are used to respond to the HTTP Digest Authentication challenge from the server.

If AuthScheme is set to NTLM, NTLM authentication will be attempted. If AuthScheme is set to NTLM and User and Password are empty, the class will attempt to authenticate using the current user's credentials.

Remarks

If this property contains a non-empty string, a Referer HTTP request header is added to the request. The purpose of the header is to show the document referring the requested URL.

This property is not available at design time.

SSLAcceptServerCert Property (REST Class)

Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.

Syntax


public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

SSLCert Property (REST Class)

The certificate to be used during SSL negotiation.

Syntax


public Certificate getSSLCert();


public void setSSLCert(Certificate SSLCert);

StatusLine Property (REST Class)

The first line of the last server response.

Syntax


public String getStatusLine();


Default Value

""

Remarks

This property contains the first line of the last server response. This value can be used for diagnostic purposes. If an HTTP error is returned when calling a method of the class, the error string is the same as the StatusLine property.

The HTTP protocol specifies the structure of the StatusLine as: [HTTP version] [Result Code] [Description].

This property is read-only and not available at design time.

Timeout Property (REST Class)

A timeout for the class.

Syntax


public int getTimeout();


public void setTimeout(int timeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If Timeout expires, and the operation is not yet complete, the class throws an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

TransferredData Property (REST Class)

The contents of the last response from the server.

Syntax


public byte[] getTransferredData();


Default Value

""

Remarks

This property contains the contents of the last response from the server. If the LocalFile is empty, the data is accumulated in TransferredData, and can also be received in the Transfer event. Otherwise, this property returns an empty string.

TransferredDataLimit controls the maximum amount of data accumulated in this property (by default there is no limit).

This property is read-only and not available at design time.

TransferredDataLimit Property (REST Class)

The maximum of bytes of data to be transferred.

Syntax


public long getTransferredDataLimit();


public void setTransferredDataLimit(long transferredDataLimit);

Default Value

0

Remarks

This property defines the maximum of bytes of data to be transferred. The default value is 0, which means there is no limit to the amount of data the class will accumulate and parse. If this value is set to a number n which is greater than 0, the class will only receive the first n bytes of data from the server.

TransferredHeaders Property (REST Class)

The full set of headers as received from the server.

Syntax


public String getTransferredHeaders();


Default Value

""

Remarks

This property returns the complete set of raw headers as received from the server.

The Header event shows the individual headers as parsed by the class.

This property is read-only and not available at design time.

If AuthScheme is set to NTLM, NTLM authentication will be attempted. If AuthScheme is set to NTLM and User and Password are empty, the class will attempt to authenticate using the current user's credentials.

Validate Property (REST Class)

When True, the parser checks that the document consists of well-formed XML.

Syntax


public boolean isValidate();


public void setValidate(boolean validate);

Default Value

True

Remarks

You can set Validate to False when you want to ignore XML format rules (e.g. while parsing HTML files).

XAttributes Property (REST Class)

A collection of attributes of the current element.

Syntax


public XMLAttributeList getXAttributes();


Remarks

This collection consists of all attributes of the current XML element. The component parses each attribute into a collection of XMLAttribute types.

This collection is indexed from 0 to size - 1.

This property is read-only and not available at design time.

XChildren Property (REST Class)

Collection of child elements of the current element.

Syntax


public XMLElementList getXChildren();


Remarks

The elements are provided in the collection in the same order they are found in the document.

This collection is indexed from 0 to size - 1.

This property is read-only and not available at design time.

XElement Property (REST Class)

The name of the current element.

Syntax


public String getXElement();


Default Value

""

Remarks

The current element is specified via the XPath property.

This property is read-only.

XErrorPath Property (REST Class)

An XPath to check the server response for errors.

Syntax


public String getXErrorPath();


public void setXErrorPath(String XErrorPath);

Default Value

""

Remarks

This property contains an XPath to check the server response for errors. If the XPath exists, an exception will be thrown containing the value of the element at the path.

XNamespace Property (REST Class)

The namespace of the current element.

Syntax


public String getXNamespace();


Default Value

""

Remarks

The current element is specified via the XPath property.

This property is read-only.

XParent Property (REST Class)

The parent of the current element.

Syntax


public String getXParent();


Default Value

""

Remarks

This property is read-only.

XPath Property (REST Class)

Provides a way to point to a specific element in the response.

Syntax


public String getXPath();


public void setXPath(String XPath);

Default Value

""

Remarks

This property provides a way to point to a specific element in the response. This property implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents.

The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location.

The following are possible values for an element accessor:

'name'A particular element name.
[i]The i-th subelement of the current element.
..the parent of the current element.

When XPath is set to a valid path, XElement points to the name of the element, with XParent, XNamespace, XPrefix, XChildren, and XText providing other properties of the element. The attributes of the current element will be contained in the Attributes collection.

BuildDOM must be set to True prior to parsing the document for the XPath functionality to be available.

Example (Setting XPath)

Document rootRestControl.XPath = "/"
Specific ElementRestControl.XPath = "/root/SubElement1/SubElement2/"
i-th ChildRestControl.XPath = "/root/[i]"

For JSON data, this will be the path to a specified value within the document. Since arrays in JSON only contain values, and no associated object name, an empty name will be used for these values. Thus, to reach an array element at position 1, the path must be set to "[1]". In addition, a root element named "json" will be added to each JSON document in the parser. Following is an example:

Simple JSON document

{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}
Example (Setting JSON XPath)

Document root RestControl.XPath = "/"
Specific Element RestControl.XPath = "/json/firstlevel/one/"
i-th Child RestControl.XPath = "/json/firstlevel/two/[i]/"

Config Method (Rest Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Delete Method (Rest Class)

If LocalFile is not empty the data (not the headers) is written there as well.

HasXPath Method (Rest Class)

Determines whether a specific element exists in the document.

Syntax

public boolean hasXPath(String XPath);

Remarks

  public byte[] text;

}

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data is being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

EncodedB
byte[]

This is the certificate (PEM/base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

ExpirationDate
String

This is the date the certificate expires. After this date, the certificate will no longer be valid. The following example illustrates the format of an encoded date:

Issuer
String

This is the issuer of the certificate. This field contains a string representation of the name of the issuing authority for the certificate.

KeyPassword
String

This is the password for the certificate's private key (if any).

Some certificate stores may individually protect certificates' private keys, separate from the standard protection offered by the StorePassword. KeyPassword. This field can be used to read such password-protected private keys.

Note: this property defaults to the value of StorePassword. To clear it, you must set the property to the empty string (""). It can be set at any time, but when the private key's password is different from the store's password, then it must be set before calling PrivateKey.

PrivateKey
String

This is the private key of the certificate (if available). The key is provided as PEM/Base64-encoded data.

Note: The PrivateKey may be available but not exportable. In this case, PrivateKey returns an empty string.

PrivateKeyAvailable
boolean

This field shows whether a PrivateKey is available for the selected certificate. If PrivateKeyAvailable is True, the certificate may be used for authentication purposes (e.g., server authentication).

PrivateKeyContainer
String

This is the name of the PrivateKey container for the certificate (if available). This functionality is available only on Windows platforms.

PublicKey
String

This is the public key of the certificate. The key is provided as PEM/Base64-encoded data.

PublicKeyAlgorithm
String

This field contains the textual description of the certificate's public key algorithm. The property contains either the name of the algorithm (e.g., "RSA" or "RSA_DH") or an object identifier (OID) string representing the algorithm.

PublicKeyLength
int

This is the length of the certificate's public key (in bits). Common values are 512, 1024, and 2048.

SerialNumber
String

This is the serial number of the certificate encoded as a string. The number is encoded as a series of hexadecimal digits, with each pair representing a byte of the serial number.

SignatureAlgorithm
String

The field contains the text description of the certificate's signature algorithm. The property contains either the name of the algorithm (e.g., "RSA" or "RSA_MD5RSA") or an object identifier (OID) string representing the algorithm.

Store
String

This is the name of the certificate store for the client certificate.

The StoreType field denotes the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

StoreB
byte[]

This is the name of the certificate store for the client certificate.

The StoreType field denotes the type of the certificate store specified by Store. If the store is password protected, specify the password in StorePassword.

Store is used in conjunction with the Subject field to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject field for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

StorePassword
String

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

StoreType
int

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This field can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.

HTTPCookie Type

An HTTP cookie either sent to or received from the server.

Remarks

An HTTP cookie can store the cookies that are to be sent to the server. It may also store the cookies set by the server.

Cookies that are to be sent to the server must have the Name and Value fields supplied prior to submitting the URL. However, when the SetCookie event is fired, all of the fields of an HTTPCookie are filled out accordingly.

Fields

Domain
String

The domain of a received cookie. This field contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, this field will contain an empty string. The convention in this case is to use the server name specified by URLServer as the cookie domain.

Expiration
String

This field contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, this field will contain an empty string. The convention is to drop the cookie at the end of the session.

Name
String

The name of the cookie.

This field, along with Value store the cookie that is to be sent to the server. The SetCookie event displays the cookies set by the server and their properties.

Path
String

This field contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the path field will be an empty string. The convention in this case is to use the path specified by URLPath as the cookie path.

Secure
boolean

This field contains the security flag of the received cookie. This field specifies whether the cookie is secure. If the value of this field is True, the cookie value must be submitted through a secure (HTTPS) connection only.

Value
String

This field contains the value of the cookie. The cookie specified by Name has a corresponding value associated with it. This property holds that value.

The SetCookie event provides the cookies set by the server.

Constructors

public HTTPCookie();



public HTTPCookie(String name, String value);



Proxy Type

The proxy the class will connect to.

Remarks

When connecting through a proxy, this type is used to specify different properties of the proxy such as the Server and the AuthScheme.

Fields

AuthScheme
int

This field is used to tell the class which type of authorization to perform when connecting to the proxy. This is only used when the User and Password fields are set.

AuthScheme should be set to authNone (3) when no authentication is expected.

By default, AuthScheme is authBasic (0), and if the User and Password fields are set, the component will attempt basic authentication.

If AuthScheme is set to authDigest (1), digest authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If AuthScheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this field will clear the values of User and Password.

AutoDetect
boolean

This field tells the class whether or not to automatically detect and use proxy system settings, if available. The default value is false.

Note: This setting is only applicable in Windows.

Password
String

This field contains a password if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

Port
int

This field contains the TCP port for the proxy Server (default 80). See the description of the Server field for details.

Server
String

If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

If the Server field is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, the Server field is set to the corresponding address. If the search is not successful, an error is returned.

SSL
int

This field determines when to use SSL for the connection to the proxy. The applicable values are the following:

psAutomatic (0)Default setting. If the URL is an "https" URL, the class will use the psTunnel option. If the URL is a "http" URL, the class will use the psNever option.
psAlways (1)The connection is always SSL-enabled.
psNever (2)The connection is not SSL-enabled.
psTunnel (3)The connection is through a tunneling (HTTP) proxy.

User
String

This field contains a user name, if authentication is to be used for the proxy.

If AuthScheme is set to Basic Authentication, the User and Password are Base64 encoded and the proxy authentication token will be generated in the form "Basic [encoded-user-password]".

If AuthScheme is set to Digest Authentication, the User and Password fields are used to respond to the Digest Authentication challenge from the server.

If AuthScheme is set to NTLM Authentication, the User and Password fields are used to authenticate through NTLM negotiation.

Constructors

public Proxy();



public Proxy(String server, int port);



public Proxy(String server, int port, String user, String password);

Remarks

This type describes an XML namespace from the current stack. It includes fields to denote the Prefix and the URI of the namespace being defined.

The default namespace exists at index 0. The Prefix field at index 0 is "xmlns", and the Name field contains the default namespace.

Fields

Prefix
String

The Prefix for the Namespace.

URI
String

Namespace URI associated with the corresponding Prefix. This is usually a URL pointing to the XML schema for the namespace.

Constructors

public XMLNamespace();



public XMLNamespace(String name, String prefix);



Configuration Settings (Rest Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

REST Configuration Settings

CacheContent:   If true, the original XML is saved in a buffer.

This config controls whether or not the component retains the entire original XML in a buffer. This is used to retain the original XML as opposed to returning generated XML after parsing. The default value is true.

From:   Allows the specification of the email address of the HTTP agent.

When this config is set, an HTTP From: header is added to the request. This header generally gives the email address of the requester of the document.

NOTE: This functionality is only available in Java and .NET.

StringProcessingOptions:   Defines options to use when processing string values.

This setting determines what additional processing is performed on string values during parsing. By default no additional processing is performed and the string is returned as is from the document. Possible values are:

0 (none - default) No additional processing is performed.
1 (unquote) Strings are unquoted (JSON only; same as 0 for XML).
2 (unescape) Any escaped sequences are unescaped.
3 (unquote and unescape) Values are both unquoted and unescaped (same as 2 for XML).

For instance, given the JSON elment "example": "value\ntest" or the XML element <flavor>cookies &amp; cream</flavor>, the following table shows the resulting XText value based on the current setting:

StringProcessingOptionJSON Output XML Output
0 (none)
"value\ntest"
cookies &amp; cream
1 (unquote)
value\ntest
cookies &amp; cream
2 (unescape)
"value
test"
cookies & cream
3 (unquote and unescape)
value
test
cookies & cream

Note that if BuildDOM is true, XML content will always be unescaped, regardless of this setting.

HTTP Configuration Settings

AcceptEncoding:   Used to tell the server which types of content encodings the client supports.

When AllowHTTPCompression is true, the class adds an "Accept-Encoding: " header to the request being sent to the server. By default, this header's value is "gzip, deflate". This config allows you to change the value of the "Accept-Encoding" header. NOTE: The class only supports gzip and deflate decompression algorithms.

AllowHTTPCompression:   This property enables HTTP compression for receiving data.

This setting enables HTTP compression for receiving data. When set to True (default), the class will accept compressed data. It will then uncompress the data it has received. The class will handle data compressed by both GZIP and Deflate compression algorithms.

When true, the class adds an "Accept-Encoding" header to the outgoing request. The value for this header can be controlled by the AcceptEncoding config. The default value for this header is "gzip, deflate".

The default value is True.

AllowHTTPFallback:   Whether HTTP/2 connections are permitted to fallback to HTTP/1.1.

This setting controls whether HTTP/2 connections are permitted to fallback to HTTP/1.1 when the server does not support HTTP/2. This setting is only applicable when HTTPVersion is set to "2.0".

If set to True (default) the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False the class throws an exception if the server does not support HTTP/2.

The default value is True.

AllowNTLMFallback:   Whether to allow fallback from Negotiate to NTLM when authenticating.

This setting only applies when AuthScheme is set to Negotiate. If set to True the class will automatically use NTLM if the server does not support Negotiate authentication. Note that the server must indicate it supports NTLM authentication via the WWW-Authenticate header for the fallback from Negotiate to NTLM to take place. The default value is False.

Append:   Whether to append data to LocalFile.

This setting determines whether data is appended when writing to LocalFile. When set to True downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is only applicable when LocalFile is set. The default value is False.

Authorization:   The Authorization string to be sent to the server.

If the Authorization property contains a non-empty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

BytesTransferred:   Contains the number of bytes transferred in the response data.

Returns the raw number of bytes from the HTTP response data, prior to the component processing the data, whether it is chunked and/or compressed. This returns the same value as the Transfer event, by BytesTransferred.

ChunkSize:   Specifies the chunk size in bytes when using chunked encoding.

This is only applicable when UseChunkedEncoding is true. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384.

CompressHTTPRequest:   Set to true to compress the body of a PUT or POST request.

If set to true, the body of a PUT or POST request will be compressed into gzip format before sending the request. The "Content-encoding" header is also added to the outgoing request.

The default value is False.

EncodeURL:   If set to true the URL will be encoded by the class.

If set to True the URL passed to the class will be URL encoded. The default value is False.

FollowRedirects:   Determines what happens when the server issues a redirect.

This option determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to 1 (always), the new URL for the object is retrieved automatically every time.

If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same, otherwise the class throws an exception.

Note that following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).

The default value is 0 (Never). In this case, redirects are never followed, and the class throws an exception instead.

Valid options are:

  • 0 - Never
  • 1 - Always
  • 2 - Same Scheme

GetOn302Redirect:   If set to true the class will perform a GET on the new location.

The default value is false. If set to true the class will perform a GET on the new location. Otherwise it will use the same HTTP method again.

HTTP2HeadersWithoutIndexing:   HTTP2 headers that should not update the dynamic header table with incremental indexing.

HTTP/2 servers maintain a dynamic table of headers and values seen over the course of a connection. Typically these headers are inserted into the table via incremental indexing (also known as HPACK, defined in RFC 7541). To tell the component not to use incremental indexing for certain headers, and thus not update the dynamic table, set this configuration option to a comma-delimited list of the header names.

HTTPVersion:   The version of HTTP used by the class.

This property specifies the HTTP version used by the class. Possible values are:

  • "1.0"
  • "1.1" (default)
  • "2.0"

When using HTTP/2 ("2.0") additional restrictions apply. Please see notes below for details.

HTTP/2 Notes

When using HTTP/2 only secure (TLS/SSL) connections are currently supported. Attempting to use a plaintext URL with HTTP/2 will result in an error.

If the server does not support HTTP/2 the class will automatically use HTTP/1.1 instead. This is done in order to provide compatibility without the need for any additional settings. To see which version was used check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.

HTTP/2 is supported on all platforms. The class will use the internal security implementation in all cases when connecting.

IfModifiedSince:   A date determining the maximum age of the desired document.

If this setting contains a non-empty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: if the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the component throws an exception

The format of the date value for IfModifiedSince is detailed in the HTTP specs. An example is: Sat, 29 Oct 2017 19:43:31 GMT.

KeepAlive:   Determines whether the HTTP connection is closed after completion of the request.

If true, the component will not send the 'Connection: Close' header. The absence of the Connection header indicates to the server that HTTP persistent connections should be used if supported. Note that not all server support persistent connections. You may also explicitly add the Keep-Alive header to the request headers by setting OtherHeaders to 'Connection: Keep-Alive'. If false, the connection will be closed immediately after the server response is received.

The default value for KeepAlive is false.

KerberosSPN:   The Service Principal Name for the Kerberos Domain Controller.

If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here.

LogLevel:   The level of detail that is logged.

This setting controls the level of detail that is logged through the Log event. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data is logged.
3 (Debug) Debug data is logged.

The value 1 (Info) logs basic information including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

MaxHeaders:   Instructs class to save the amount of headers specified that are returned by the server after a Header event has been fired.

This config should be set when the TransferredHeaders collection is to be populated when a Header event has been fired. This value represents the number of headers that are to be saved in the collection.

To save all items to the collection, set this config to -1. If no items are wanted, set this to 0, which will not save any to the collection. The default for this config is -1, so all items will be included in the collection.

MaxHTTPCookies:   Instructs class to save the amount of cookies specified that are returned by the server when a SetCookie event is fired.

This config should be set when populating the Cookies collection as a result of an HTTP request. This value represents the number of cookies that are to be saved in the collection.

To save all items to the collection, set this config to -1. If no items are wanted, set this to 0, which will not save any to the collection. The default for this config is -1, so all items will be included in the collection.

MaxRedirectAttempts:   Limits the number of redirects that are followed in a request.

When FollowRedirects is set to any value besides frNever the class will follow redirects until this maximum number of redirect attempts are made. The default value is 20.

NegotiatedHTTPVersion:   The negotiated HTTP version.

This setting may be queried after the request is complete to indicate the HTTP version used. When HTTPVersion is set to "2.0" if the server does not support "2.0" the class will fallback to using "1.1" automatically. This setting will indicate which was used.

OtherHeaders:   Other headers as determined by the user (optional).

This configuration option can be set to a string of headers to be appended to the HTTP request headers.

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this configuration option with caution. If this configuration option contains invalid headers, HTTP requests may fail.

This configuration option is useful for extending the functionality of the class beyond what is provided.

ProxyAuthorization:   The authorization string to be sent to the proxy server.

Similar to the Authorization config, but for proxy authorization. If this config contains a non-empty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy authorization information to the server. If User and Password are specified, this value is calculated using the algorithm specified by AuthScheme.

ProxyAuthScheme:   The authorization scheme to be used for the proxy.

This setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPassword:   A password if authentication is to be used for the proxy.

This setting is provided for use by classs that do not directly expose Proxy properties.

ProxyPort:   Port for the proxy server (default 80).

This setting is provided for use by classs that do not directly expose Proxy properties.

ProxyServer:   Name or IP address of a proxy server (optional).

This setting is provided for use by classs that do not directly expose Proxy properties.

ProxyUser:   A user name if authentication is to be used for the proxy.

This setting is provided for use by classs that do not directly expose Proxy properties.

SentHeaders:   The full set of headers as sent by the client.

This configuration setting returns the complete set of raw headers as sent by the client.

StatusLine:   The first line of the last response from the server.

This setting contains the first line of the last response from the server. The format of the line will be [HTTP version] [Result Code] [Description].

TransferredData:   The contents of the last response from the server.

This setting contains the contents of the last response from the server.

TransferredDataLimit:   The maximum number of incoming bytes to be stored by the class.

If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise this reflects the maximum number of incoming bytes that can be stored by the class.

TransferredHeaders:   The full set of headers as received from the server.

This configuration setting returns the complete set of raw headers as received from the server.

TransferredRequest:   The full request as sent by the client.

This configuration setting returns the full request as sent by the client. For performance reasons, the request is not normally saved. Set this config to ON before making a request to enable it. Examples are below.

.NET Http http = new Http(); http.Config("TransferredRequest=on"); http.PostData = "body"; http.Post("http://someserver.com"); Console.WriteLine(http.Config("TransferredRequest")); C++ HTTP http; http.Config("TransferredRequest=on"); http.SetPostData("body", 5); http.Post("http://someserver.com"); printf("%s\r\n", http.Config("TransferredRequest"));

UseChunkedEncoding:   Enables or Disables HTTP chunked encoding for transfers.

If UseChunkedEncoding is set to true, the class will use HTTP chunked encoding when posting if possible. HTTP chunked encoding allows large files to be sent in chunks instead of all at once. If set to false, the class will not use HTTP chunked encoding. The default value is false.

Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.

UseIDNs:   Whether to encode hostnames to internationalized domain names.

This setting specifies whether hostnames containing non-ASCII characters are encoded to internationalized domain names. When set to True if a hostname contains non-ASCII characters it is encoded using Punycode to an IDN.

The default value is False and the hostname will always be used exactly as specified.

UsePlatformDeflate:   Whether to use the platform implementation to decompress compressed responses.

This setting specifies whether the platform deflate algorithm implementation is used to decompress responses that use compression. If set to True (default) the platform implementation is used. If set to False an internal implementation is used.

UsePlatformHTTPClient:   Whether or not to use the platform HTTP client.

If True, the component will use the default HTTP client for the platform (URLConnection in Java, WebRequest in .NET, or CFHTTPMessage in Mac/iOS) instead of the internal HTTP implementation. This is important for environments where direct access to sockets is limited or not allowed (as in the Google AppEngine for instance).

UserAgent:   Information about the user agent (browser).

This is the value supplied in the HTTP User-Agent header. The default setting is "IPWorks HTTP Component - www.nsoftware.com".

Override the default with the name and version of your software.

IPPort Configuration Settings

CloseStreamAfterTransfer:   If true, the component will close the upload or download stream after the transfer.

This setting determines whether the input or output stream is closed after the transfer completes. When set to True (default), all streams will be closed after a transfer is completed. In order to keep streams open after the transfer of data, set this to False. the default value is True.

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallListener:   If true, the component binds to a SOCKS firewall as a server (IPPort only).

This entry is for IPPort only and does not work for other components that descend from IPPort.

If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.

RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.

The connection to the firewall is made by calling the Connect method.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class throws an exception.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

Note that the FirewallPort is set automatically when FirewallType is set to a valid value.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

The appropriate values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class throws an exception.

NOTE: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to true. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to true. By default the operating system will determine the time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires.

In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This setting optionally specifies a semicolon separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When true, the socket will send all data that is ready to send at once. When false, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this config is set to false.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are:

0 IPv4 Only
1 IPv6 Only
2 IPv6 with IPv4 fallback

UseNTLMv2:   Whether to use NTLM V2.

When authenticating with NTLM this setting specifies whether NTLM V2 is used. By default this value is False and NTLM V1 will be used. Set this to True to use NTLM V2.

SSL Configuration Settings

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When the UseInternalSecurityAPI configuration setting is True, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if UseInternalSecurityAPI is False.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the class will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the class is the same.

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w
F0I1XhM+pKj7FjDr+XNj
-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----
MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp
..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the class will check the Certificate Revocation List specified by the server certificate. If set to true the class will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the class throws an exception.

When set to false (default) the CRL check will not be performed by the class.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLContextProtocol:   The protocol used when getting an SSLContext instance.

Possible values are SSL, SSLv2, SSLv3, TLS and TLSv1. Use it only in case your security provider does not support TLS. This is the parameter "protocol" inside the SSLContext.getInstance(protocol) call.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Note: This value must be set after UseInternalSecurityAPI is set.

Example values: obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA"); obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA; SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA"); Possible values when UseInternalSecurityAPI is False (default) include:

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList setting.

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when UseInternalSecurityAPI is set to true.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

SSLKeyLogFile:   The location of a file where per-session secrets are written for debugging purposes.

This setting optionally specifies the full path to a file on disk where per-session secrets are stored for debugging purposes.

When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.

Note: This setting is only applicable when UseInternalSecurityAPI is set to True.

SSLNegotiatedCipher:   Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipher[connId]");

SSLNegotiatedCipherStrength:   Returns the negotiated ciphersuite strength.

Returns the strength of the ciphersuite negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherStrength[connId]");

SSLNegotiatedCipherSuite:   Returns the negotiated ciphersuite.

Returns the ciphersuite negotiated during the SSL handshake represented as a single string.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedCipherSuite[connId]");

SSLNegotiatedKeyExchange:   Returns the negotiated key exchange algorithm.

Returns the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchange[connId]");

SSLNegotiatedKeyExchangeStrength:   Returns the negotiated key exchange algorithm strength.

Returns the strenghth of the key exchange algorithm negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedKeyExchangeStrength[connId]");

SSLNegotiatedProtocol:   Returns the negotiated protocol version.

Returns the protocol version negotiated during the SSL handshake.

Note: For server components (e.g. IPDaemon) this is a per-connection setting accessed by passing the ConnectionId. For example: server.Config("SSLNegotiatedProtocol[connId]");

SSLProvider:   The name of the security provider to use.

Change this setting to use security providers other than the system default.

Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application.

The special value "*" (default) picks the default SSL provider defined in the system.

The special value "Internal" picks the internal SSL implementation. This does not rely on any system libraries. This is equivalent to setting UseInternalSecurityAPI to True.

Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed except to a value of "Internal".

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:

-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

-----END CERTIFICATE-----
\r \n
-----BEGIN CERTIFICATE-----

..
d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA
-----END CERTIFICATE-----

SSLTrustManagerFactoryAlgorithm:   The algorithm to be used to create a TrustManager through TrustManagerFactory.

Possible values include SunX509. This is the parameter "algorithm" inside the TrustManagerFactory.getInstance(algorithm) call.

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is True and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class throws an exception.

The format of this value is a comma separated list of hash-signature combinations. For instance: IPPort.Config("UseInternalSecurityAPI=true"); IPPort.Config("SSLEnabledProtocols=3072"); //TLS 1.2 IPPort.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa"); The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13Provider:   The TLS 1.3 implementation to be used.

This setting specifies the TLS 1.3 implementation which will be used when TLS 1.3 is enabled via SSLEnabledProtocols. Possible values are:

  • 0 (Internal - Default)
  • 1 (Platform)

The platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.

If set to 1 (Platform provider) please be aware of the following notes:

  • The platform provider is only available on Windows 11 / Windows Server 2022 and up.
  • SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
  • If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
  • "rsa_pkcs1_sha512" (default)
  • "rsa_pss_sha256" (default)
  • "rsa_pss_sha384" (default)
  • "rsa_pss_sha512" (default)
The default value is rsa_pss_sha256,rsa_pss_sha384,rsa_pss_sha512,rsa_pkcs1_sha256,rsa_pkcs1_sha384,rsa_pkcs1_sha512,ecdsa_secp256r1_sha256,ecdsa_secp384r1_sha384,ecdsa_secp521r1_sha512,ed25519,ed448. This setting is only applicable when SSLEnabledProtocols includes TLS 1.3.
TLS13SupportedGroups:   The supported groups for (EC)DHE key exchange.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. This setting should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448" (default)
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096" (default)
  • "ffdhe_6144" (default)
  • "ffdhe_8192" (default)

Socket Configuration Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for UDP ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Configuration Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Tells the class whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
UseDaemonThreads:   Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions. Setting this to True tells the class to use the internal implementation instead of using the system's security API.
