WebDAV Class
Properties Methods Events Config Settings Errors
The WebDAV Class implements an easy-to-use interface to the Web Distributed Authoring and Versioning (WebDAV) protocol.
Syntax
ipworksssl.WebDAV
Remarks
The WebDAV Class is designed to interact with the Web Distributed Authoring and Versioning (WebDAV) protocol. This class offers robust support for both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (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 through the Config method.
Remote Resource Management
The WebDAV Class enables remote management of resource properties and collections, offering a comprehensive set of operations including creation, deletion, listing, copying, moving, and resource locking.
Listing Directories
The ListDirectory method is used to list the resources from a specific URI. Depending on the Depth property (see below) the scope of the list changes. For each resource found, the class fires the DirList once and also populates the Resources collection.
Downloading Resources
The GetResource method is used to retrieve the data of a resource from a WebDAV server. The data is stored in the stream specified using SetDownloadStream, the file from the LocalFile property, or the TransferredData property respectively.
Uploading Resources
The PutResource method is used to send data to the WebDAV server using the PUT method to the specified resource URI. The data is taken from the the stream specified using SetUploadStream or the file from the LocalFile property.
Finding Properties
The FindProperties method is used to find the properties of a specific resource (or multiple resource depending on the Depth property). This search can be filtered by adding items to the Properties collection, one item for each property. This method will populate then populate the Properties collection (clearing the collection) and fire the ResourceProperties event once for each found property.
Depth
Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return the response HTTP 403 Forbidden.
Namespaces
A number of operations can be performed on resources by using the various methods of the class. Please refer to the individual methods for more information. WebDAV allows nonstandard properties to be specified through XML namespaces.The namespaces are provided in the Namespaces collection, which is filled automatically when retrieving DAV responses, but must be filled manually when requesting nonstandard properties.

Accept Property (WebDAV Class)
This property includes 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 nonempty 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 (WebDAV Class)
This property includes 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 nonempty 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 (WebDAV Class)
This property specifies the authentication scheme to use when server authentication 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 HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.
If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.
If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.
Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the class.
For security, changing the value of this property will cause the class to clear the values of User, Password, and Authorization.
Connected Property (WebDAV Class)
This property shows whether the class is connected.
Syntax
public boolean isConnected();
Default Value
False
Remarks
This property is used to determine whether or not the class is connected to the remote host. Use the Connect and Disconnect methods to manage the connection.
This property is read-only and not available at design time.
Cookies Property (WebDAV Class)
This property includes a 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 also are 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.
Please refer to the HTTPCookie type for a complete list of fields.Depth Property (WebDAV Class)
This property specifies the depth associated with the current operation.
Syntax
public int getDepth(); public void setDepth(int depth); Enumerated values: public final static int dpUnspecified = 0; public final static int dpResourceOnly = 1; public final static int dpImmediateChildren = 2; public final static int dpInfinity = 3;
Default Value
0
Remarks
When performing certain operations on resource collections, the class will use Depth to instruct the server about how deep to operate within the collection. Depth is an enumerated type with the following possible values:
dpUnspecified (0) | The server will use the protocol default depth for the operation (this is normally infinity). |
dpResourceOnly (1) | The server will operate only on the collection resource URI and not on any of its internal member resources. |
dpImmediateChildren (2) | The server will operate on the collection resource URI and all of its immediate member resources (but on none of their member resources). |
dpInfinity (3) | The server will recursively operate on the target resource URI and all of its internal member URIs through all levels of the collection hierarchy. |
Depth is used when performing the following operations: LockResource, MoveResource CopyResource, FindProperties, PatchProperties, and ListDirectory.
Firewall Property (WebDAV 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.
Please refer to the Firewall type for a complete list of fields.FollowRedirects Property (WebDAV Class)
This property 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: 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 potentially could change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty. If, however, this property is set to frAlways (1), 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.
Idle Property (WebDAV Class)
This property specifies 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 or waiting for an answer), and True at all other times.
This property is read-only.
LocalFile Property (WebDAV Class)
This property includes the path to a local file used for DAV operations.
Syntax
public String getLocalFile(); public void setLocalFile(String localFile);
Default Value
""
Remarks
After a GetResource operation, LocalFile will contain the contents of the resource.
For a PutResource operation, LocalFile contains the data that will be uploaded to the server.
If LocalFile is empty, then the received data are provided through the Transfer event.
LocalHost Property (WebDAV Class)
This property includes 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 multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
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 multihomed 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.
LockOwner Property (WebDAV Class)
This property specifies the principle that owns the current resource lock.
Syntax
public String getLockOwner(); public void setLockOwner(String lockOwner);
Default Value
""
Remarks
Before making a call to the LockResource method, LockOwner may be set to the name of a principle or group of principles that will own the lock. If no owner is specified, the server will automatically associate the lock with the requesting principle. After a successful LockResource operation, the class will set the LockOwner property to the correct value returned in the server's response.
LockScope Property (WebDAV Class)
This property specifies the scope of the current resource lock.
Syntax
public String getLockScope(); public void setLockScope(String lockScope);
Default Value
""
Remarks
Before making a call to the LockResource method, LockScope may be set to the type of scope needed for the lock. Currently, the class will allow only two types of scopes to be requested:
exclusive | The lock belongs exclusively to the requesting principle. No other principle may modify the locked resource URI. |
shared | The locked resource may not be modified by nontrusted principles. Users who have access rights, however, may request a shared lock that they can use to modify or operate on the resource. |
If no scope is specified, the protocol default scope, exclusive, will be requested. After a successful LockResource operation, the class will set the LockScope property to the correct value returned in the server's response.
LockTimeout Property (WebDAV Class)
This property includes the time to live for the current resource lock.
Syntax
public int getLockTimeout(); public void setLockTimeout(int lockTimeout);
Default Value
0
Remarks
Before a call to the LockResource method, LockTimeout may be set to a specific amount of time needed for the locked operation to take place. The timeout is used to determine how long the lock may exist before the server automatically unlocks the resource URI. If Timeout of 0 is specified, the server will use a default timeout. After a successful LockResource operation, the class will set the LockTimeout property to the correct value returned in the server's response.
LockToken Property (WebDAV Class)
The lock string to be used when submitting operations on a locked resource.
Syntax
public String getLockToken(); public void setLockToken(String lockToken);
Default Value
""
Remarks
Before a call to the LockResource method, LockToken may be set to the token returned by a previous lock operation. This is useful when renewing a timeout. The server will respond with a new timeout value, which will be stored in LockTimeout. If the lock request is not a lock refresh, LockToken must be empty, and they will be parsed out of the server response after a successful call to the LockResource method.
LockType Property (WebDAV Class)
This property specifies the type of the current resource lock.
Syntax
public String getLockType(); public void setLockType(String lockType);
Default Value
"write"
Remarks
Before making a call to the LockResource method, LockType may be set to the type of lock being requested. Currently, the class supports only requesting locks of type write, although the protocol defines an optional read lock. After a successful LockResource operation, the class will set the LockType property to the correct value returned in the server's response.
Namespaces Property (WebDAV Class)
This property includes the collection of namespaces in the current stack.
Syntax
public XMLNamespaceList getNamespaces(); public void setNamespaces(XMLNamespaceList namespaces);
Remarks
WebDAV allows nonstandard properties to be specified through XML namespaces.
The collection is filled automatically when retrieving DAV responses, but it must be filled manually when requesting nonstandard properties.
If the DAV URI is not found in the namespaces collection, it will be added as the default namespace when generating a request. The DAV namespace URI is DAV:.
This collection is indexed from 0 to size -1.
This property is not available at design time.
Please refer to the XMLNamespace type for a complete list of fields.OtherHeaders Property (WebDAV Class)
This property includes other headers as determined by the user (optional).
Syntax
public String getOtherHeaders(); public void setOtherHeaders(String otherHeaders);
Default Value
""
Remarks
This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like ContentType and From.
The headers must follow 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 (WebDAV Class)
This property includes a 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.
Please refer to the Header type for a complete list of fields.Password Property (WebDAV Class)
This property includes 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 configuration 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.
Properties Property (WebDAV Class)
This property includes a collection of WebDAV properties.
Syntax
public DAVPropertyList getProperties(); public void setProperties(DAVPropertyList properties);
Remarks
The property names provided in the Properties collection are used by the FindProperties and PatchProperties methods.
After a call to FindProperties, the Properties collection will contain the name, value, and status of the DAV property returned by the server. The contents of the collection change for every matching resource (ResourceProperties event). After the call completes, the collection will contain the values of the last matching resource.
When a call is made to PatchProperties, the class will use the operations provided in the Properties collection to tell the server what to do with the properties under the following scheme:
opNone (0) | No operation will be performed on the property. |
opSet (1) | The value of Name will be set to Value. |
opDelete (2) | The property defined by Name will be removed from its resource. |
This collection is indexed from 0 to size -1.
Please refer to the DAVProperty type for a complete list of fields.Proxy Property (WebDAV Class)

Default Value
""
Remarks
If this property contains a nonempty 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.
ResourceData Property (WebDAV Class)
Specifies the data to be uploaded to the webDAV server.
Syntax
public byte[] getResourceData(); public void setResourceData(byte[] resourceData);
Default Value
""
Remarks
This property specifies the data to be uploaded to the webDAV server. If neither the SetUploadStream nor LocalFile are specified, the data specified in this property will be uploaded to the designated resource when the PutResource method is called.
This property is not available at design time.
Resources Property (WebDAV Class)
This property includes a collection of resources resulting from the last directory listing.
Syntax
public DAVResourceList getResources();
Remarks
This property contains a list of resources listed by the server after a call to the ListDirectory method. To retrieve properties of a particular resource, please refer to the FindProperties method.
MaxResources can be used to control the number of resource listings saved.
This collection is indexed from 0 to size -1.
This property is read-only.
Please refer to the DAVResource type for a complete list of fields.SSLAcceptServerCert Property (WebDAV Class)
This property 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.
Note: This functionality is provided only for cases in which 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.
Please refer to the Certificate type for a complete list of fields.SSLCert Property (WebDAV Class)
This property includes the certificate to be used during Secure Sockets Layer (SSL) negotiation.
Syntax
public Certificate getSSLCert(); public void setSSLCert(Certificate SSLCert);
Remarks
This property includes the digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.
Please refer to the Certificate type for a complete list of fields.SSLProvider Property (WebDAV Class)
This property specifies the Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.
Syntax
public int getSSLProvider(); public void setSSLProvider(int SSLProvider); Enumerated values: public final static int sslpAutomatic = 0; public final static int sslpPlatform = 1; public final static int sslpInternal = 2;
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are as follows:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.
When Automatic is selected, the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used.
SSLServerCert Property (WebDAV Class)
This property includes the server certificate for the last established connection.
Syntax
public Certificate getSSLServerCert();
Remarks
SSLServerCert contains the server certificate for the last established connection.
SSLServerCert is reset every time a new connection is attempted.
This property is read-only.
Please refer to the Certificate type for a complete list of fields.StatusLine Property (WebDAV Class)
This property is 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 follows: [HTTP version] [Result Code] [Description].
This property is read-only and not available at design time.
Timeout Property (WebDAV Class)
This property includes the 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.
Note: By default, all timeouts are inactivity timeouts, that is, 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 (WebDAV Class)
This property includes 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 are accumulated in TransferredData and also can be received in the Transfer event. Otherwise, this property returns an empty string.
TransferredDataLimit controls the maximum amount of data accumulated in TransferredData (by default there is no limit).
This property is read-only and not available at design time.
TransferredHeaders Property (WebDAV Class)
This property includes 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.
User Property (WebDAV Class)
This property includes a user name if authentication is to be used.
Syntax
public String getUser(); public void setUser(String user);
Default Value
""
Remarks
This property contains a user name 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 property 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.
AddCookie Method (WebDAV Class)
This method adds a cookie and the corresponding value to the outgoing request headers.
Syntax
public void addCookie(String cookieName, String cookieValue);
Remarks
This property adds a cookie and the corresponding value to the outgoing request headers. Please refer to the Cookies property for more information on cookies and how they are managed.
AddNamespace Method (WebDAV Class)
This method adds a namespace to the Namespaces properties.
Syntax
public void addNamespace(String prefix, String namespaceURI);
Remarks
Prefix specifies the namespace prefix, and NamespaceURI specifies the namespace.
CheckFileExists Method (WebDAV Class)
Checks if a file exists in the specified URI.
Syntax
public boolean checkFileExists(String resourceURI);
Remarks
This method returns true if the file exists on the specific endpoint provided by the ResourceURI parameter. It returns false if the file does not exist.
Config Method (WebDAV 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.
CopyResource Method (WebDAV Class)
This method copies a resource to a new location.
Syntax
public void copyResource(String sourceResourceURI, String destinationResourceURI);
Remarks
The CopyResource method will copy the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI using the WebDAV COPY method.
This method is associated with the Depth property. If Depth is set to 0, the class will copy only SourceResourceURI. If Depth is set to infinity, the class will copy SourceResourceURI and its entire subtree to locations relative to it.
If the user has acquired a LockResource of infinite depth on either DestinationResourceURI or any collection it is under, SourceResourceURI will be added to that lock.
DeleteResource Method (WebDAV Class)
This method deletes a resource.
Syntax
public void deleteResource(String resourceURI);
Remarks
The resource or collection specified by ResourceURIis deleted using the WebDAV DELETE method. The DeleteResource method behaves independently of the Depth property. If ResourceURI denotes a collection, the server behaves as if the command were issued with an infinite depth (i.e., all internal member URIs denoting single resources or collections are deleted). If ResourceURI denotes a non-collection resource, it is first removed from any collection that it contains, and then the resource is removed from the server.
DoEvents Method (WebDAV Class)
This method processes events from the internal message queue.
Syntax
public void doEvents();
Remarks
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
FindProperties Method (WebDAV Class)
This method is used to get resource property values from the server.
Syntax
public void findProperties(String resourceURI);
Remarks
This method fetches the properties for the resources using the WebDAV PROPFIND method. If there are properties (with names) set in the Properties collection then the values for only those properties will be requested. If no properties are set in the Properties collection, then the all the properties for the specified resource will be requested.
The response will populate the Properties collection and will fire the ResourceProperties event once for each property returned.
Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.
Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return the response HTTP 403 Forbidden.
FindPropertyNames Method (WebDAV Class)
This method is used to get resource property names from the server.
Syntax
public void findPropertyNames(String resourceURI);
Remarks
FindPropertyNames will request names of all the properties of ResourceURI. The matching URIs will be returned through one or more ResourceProperties events (one for each matching resource), and the property names will be provided through the Properties collection.
Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.
Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return the response HTTP 403 Forbidden.
GetProperty Method (WebDAV Class)
This method is used to get the value for a particular property.
Syntax
public String getProperty(String propertyName);
Remarks
The class will search through its internal Properties collection for the property identified by PropertyName and will return the value associated with it.
PropertyName may also be a partial XPath expression to the retrieved resource XML. This method is useful for reading values of composite properties.
Note: This method does not make a request to the WebDAV server for a list of properties. The FindProperties method must be called first to issue the WebDAV PROPFIND request and populate the Properties collection.
GetResource Method (WebDAV Class)
This method uses a WebDAV GET method to get a resource.
Syntax
public void getResource(String resourceURI);
Remarks
This method requests a resource using the WebDAV GET method. When the DAV server responds, the resource contents are delivered through the Transfer event, and the HTTP response headers are delivered through the Header event. Additionally, the resource contents are saved to the stream specified using SetDownloadStream, the specified LocalFile, or the TransferredData property respectively.
Interrupt Method (WebDAV Class)
This method interrupts the current method.
Syntax
public void interrupt();
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
ListDirectory Method (WebDAV Class)
This method lists the files and subdirectories of the ResourceURI .
Syntax
public void listDirectory(String resourceURI);
Remarks
This method will return a list of resources from the specified URI. The results will be returned through one or more DirList events (one for each matching resource).
Depth is used to determine which resources or properties are retrieved from the server. A depth of ResourceOnly will return only the resource associated with ResourceURI, or its properties. A depth of Infinity will return all resources contained within hierarchy, or their collective properties.
Note: Some servers (such as IIS 7.5) may not support a depth of Infinity by default and may return the response HTTP 403 Forbidden.
LockResource Method (WebDAV Class)
This method is used to obtain a lock for a specified resource.
Syntax
public void lockResource(String resourceURI);
Remarks
The LockResource method will request a new lock to be placed on ResourceURI in the user's name so that only the user can operate on it. The method is linked to a number of properties that it uses to generate the lock request:
LockOwner | The principle that will own the lock. |
LockScope | The scope of the lock. Currently, the class supports only locks of scope exclusive and shared. |
LockTimeout | The amount of time that the lock is allowed to exist before ResourceURI is automatically unlocked by the server. |
LockToken | The lock itself. If the user sets this before making the request, the timeout on the existing lock will be refreshed (reset to 0). Otherwise, a new set of lock token will be returned. |
LockType | The type of lock. Currently, the class supports only type write. |
This method is associated with the Depth property. If Depth is set to 0, the class will lock only ResourceURI and its properties. If Depth is set to infinity, the class will lock ResourceURI and its entire subtree.
If MoveResource or CopyResource are used to place a resource or collection in a location under a resource locked with infinity, the new resource or collection will be added to the lock. Any lock on a collection will prevent nonlock owners from adding resources to that collection.
MakeDirectory Method (WebDAV Class)
This method can be used to make a new directory.
Syntax
public void makeDirectory(String resourceURI);
Remarks
A new resource collection is created at the location specified by ResourceURI.
MoveResource Method (WebDAV Class)
This method moves one resource to a new location.
Syntax
public void moveResource(String sourceResourceURI, String destinationResourceURI);
Remarks
The MoveResource method will move the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.
This method is associated with the Depth property. If Depth is set to 0, the class will move only SourceResourceURI. If Depth is set to infinity, the class will move SourceResourceURI and its entire subtree to locations relative to it.
If the user has acquired a LockResource of infinite depth on either DestinationResourceURI or any collection it is under, SourceResourceURI will be added to that lock.
PatchProperties Method (WebDAV Class)
This method updates the current set of properties on the server.
Syntax
public void patchProperties(String resourceURI);
Remarks
When the user calls PatchProperties, the class will send a request to the server to update the existing property list. The method is linked to the Properties property: the class will use the Operation field to tell the server what to do with the properties.
PostToResource Method (WebDAV Class)
This method posts data to a resource using the WebDAV POST method.
Syntax
public void postToResource(String resourceURI);
Remarks
This method posts data to the resource ResourceURI using the WebDAV POST method. The posted data are taken from ResourceData. The server response text is received through the Transfer event, and the HTTP response headers are received through the Header event. If LocalFile property is not empty, the data (not the headers) are written there as well.
PutResource Method (WebDAV Class)
This method sends data to the server using the PUT method.
Syntax
public void putResource(String resourceURI);
Remarks
The data are taken from LocalFile. The server will normally require authentication for this operation, so User and Password must have valid values before the request is made.
Reset Method (WebDAV Class)
This method will reset the class.
Syntax
public void reset();
Remarks
This method will reset the class's properties to their default values.
SendCustomRequest Method (WebDAV Class)
This method sends a custom request to the WebDAV server.
Syntax
public void sendCustomRequest(String httpMethod, String url, String requestBody);
Remarks
This method can be used to send arbitrary requests to a WebDAV server.
Valid values for HttpMethod are:
- GET (default if empty)
- HEAD
- POST
- PUT
- PATCH
- PROPFIND
- PROPPATCH
- MKCOL
- COPY
- MOVE
- LOCK
- UNLOCK
The value passed for URL is used as the location the request is made to. The RequestBody parameter is used to provide the component with the request body for the request. If no request body is needed for the request, the RequestBody parameter should also then be set to an empty string. If preferred, the request body can be provided via the LocalFile property instead. When doing so, the RequestBody parameter must be set to an empty string.
Note, the LocalFile property is not cleared after the request is made and should be cleared by either calling Reset or be setting it to an empty string.
When the server responds, the class stores the response headers in the ParsedHeaders collection and the response body in the stream specified using SetDownloadStream, the specified LocalFile, or the TransferredData property (using the same logic as GetResource). If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.
SetDownloadStream Method (WebDAV Class)
This method sets the stream to which the downloaded data from the server will be written.
Syntax
public void setDownloadStream(java.io.OutputStream downloadStream);
Remarks
If a download stream is set before the GetResource method is called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.
The class will automatically close this stream if CloseStreamAfterTransfer is True (default). If the stream is closed, you will need to call SetDownloadStream again before calling GetResource again.
The downloaded content will be written starting at the current position in the stream.
SetProperty Method (WebDAV Class)
This method sets the value of a property.
Syntax
public void setProperty(String propertyName, String propertyValue);
Remarks
This method is used to set a single property to a certain value. The name and new value of the property must be supplied in the parameters for this method.
Note: This is the same as calling the PatchProperties on one property when the operation is opSet.
Example. Set Property:
Control.SetProperty("MyProperty", "MyValue")
is equivalent to:
Control.Properties.Add(new DAVProperty())
Control.Properties[0].Name = "MyProperty"
Control.Properties[0].Value = "MyValue"
Control.Properties[0].Operation = DAVPropertyOperations.opSet
Control.PatchProperties()
SetUploadStream Method (WebDAV Class)
This method sets the stream to be uploaded to the server.
Syntax
public void setUploadStream(java.io.InputStream uploadStream);
Remarks
If an upload stream is set before data are to be uploaded to the server, the content of the stream will be read by the class and uploaded to the server. The stream should be open and normally set to position 0.
The class will automatically close this stream if CloseStreamAfterTransfer is True (default). If the stream is closed, you will need to call SetUploadStream again before calling the PutResource/PostToResource again.
The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.
UnLockResource Method (WebDAV Class)
This method unlocks a resource.
Syntax
public void unLockResource(String resourceURI);
Remarks
Before calling UnLockResource on a particular resource, the LockToken property must be set to the lock token for ResourceURI. The method will remove the lock, allowing other users or nonprivileged users to access and operate on the file.
Connected Event (WebDAV Class)
This event is fired immediately after a connection completes (or fails).
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void connected(WebDAVConnectedEvent e) {} ... } public class WebDAVConnectedEvent { public int statusCode; public String description; }
Remarks
If the connection is made normally, StatusCode is 0 and Description is "OK".
If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error.
Please refer to the Error Codes section for more information.
ConnectionStatus Event (WebDAV Class)
This event is fired to indicate changes in the connection state.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void connectionStatus(WebDAVConnectionStatusEvent e) {} ... } public class WebDAVConnectionStatusEvent { public String connectionEvent; public int statusCode; public String description; }
Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |

Remarks
The DirList event is fired when a directory listing is received as a response to ListDirectory.
The StartTransfer and EndTransfer events mark the beginning and the end of the event stream.
Disconnected Event (WebDAV Class)
This event is fired when a connection is closed.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void disconnected(WebDAVDisconnectedEvent e) {} ... } public class WebDAVDisconnectedEvent { public int statusCode; public String description; }
Remarks
If the connection is broken normally, StatusCode is 0 and Description is "OK".
If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.
Please refer to the Error Codes section for more information.
EndTransfer Event (WebDAV Class)
This event is fired when a document finishes transferring.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void endTransfer(WebDAVEndTransferEvent e) {} ... } public class WebDAVEndTransferEvent { public int direction; }

The Direction parameter shows whether the client (0) or the server (1) is sending the data.
Error Event (WebDAV Class)
Fired when information is available about errors during data delivery.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void error(WebDAVErrorEvent e) {} ... } public class WebDAVErrorEvent { public int errorCode; public String description; }
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
Header Event (WebDAV Class)
This event is fired every time a header line comes in.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void header(WebDAVHeaderEvent e) {} ... } public class WebDAVHeaderEvent { public String field; public String value; }
Remarks
The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

Log Event (WebDAV Class)
This event fires once for each log message.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void log(WebDAVLogEvent e) {} ... } public class WebDAVLogEvent { public int logLevel; public String message; public String logType; }
Remarks
This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are 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).
Message is the log entry.
LogType identifies the type of log entry. Possible values are as follows:
- "Info"
- "RequestHeaders"
- "ResponseHeaders"
- "RequestBody"
- "ResponseBody"
- "ProxyRequest"
- "ProxyResponse"
- "FirewallRequest"
- "FirewallResponse"
Redirect Event (WebDAV Class)
This event is fired when a redirection is received from the server.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void redirect(WebDAVRedirectEvent e) {} ... } public class WebDAVRedirectEvent { public String location; public boolean accept; //read-write }
Remarks
This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the class throws an exception. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.
ResourceProperties Event (WebDAV Class)
This event fires for each entry returned through a property search.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void resourceProperties(WebDAVResourcePropertiesEvent e) {} ... } public class WebDAVResourcePropertiesEvent { public String resourceURI; public String resourceProperties; }
Remarks
The ResourceProperties event is fired when resource properties are received as a response to FindProperties.
The StartTransfer and EndTransfer events mark the beginning and end of the event stream.
The ResourceProperties contains the full XML containing the properties of the resource.
ResourceURI contains the name of the resource.
The parsed property names, values, and status are contained within the Properties collection.
SetCookie Event (WebDAV Class)
This event is fired for every cookie set by the server.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void setCookie(WebDAVSetCookieEvent e) {} ... } public class WebDAVSetCookieEvent { public String name; public String value; public String expires; public String domain; public String path; public boolean secure; }
Remarks
The SetCookie event is fired for every Set-Cookie: header received from the HTTP server.
The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.
The Expires parameter 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, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.
The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.
The Path parameter 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 parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.
The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.
SSLServerAuthentication Event (WebDAV Class)
Fired after the server presents its certificate to the client.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void SSLServerAuthentication(WebDAVSSLServerAuthenticationEvent e) {} ... } public class WebDAVSSLServerAuthenticationEvent { public byte[] certEncoded; public String certSubject; public String certIssuer; public String status; public boolean accept; //read-write }
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (WebDAV Class)
Fired when secure connection progress messages are available.
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void SSLStatus(WebDAVSSLStatusEvent e) {} ... } public class WebDAVSSLStatusEvent { public String message; }
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (WebDAV Class)
This event is fired when a document starts transferring (after the headers).
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void startTransfer(WebDAVStartTransferEvent e) {} ... } public class WebDAVStartTransferEvent { public int direction; }
Remarks
The StartTransfer event is fired when the document text starts transferring from the server to the local host.

Transfer Event (WebDAV Class)
This event is fired while a document transfers (delivers document).
Syntax
public class DefaultWebDAVEventListener implements WebDAVEventListener { ... public void transfer(WebDAVTransferEvent e) {} ... } public class WebDAVTransferEvent { public int direction; public long bytesTransferred; public int percentDone; public byte[] text; }
Remarks
The Text parameter contains the portion of the document text being received. It is empty if data are 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: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect 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.

In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.WebDAV Config Settings
webdav.ListDirectory("https://localhost/DAV/");
bool isDir = Convert.ToBoolean(webdav.Config("IsDir[0]"));
An exception will be thrown if an invalid index is specified.
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
Normally, servers will return all properties for a resource, but in some cases, it is costly to get certain properties. It is perfectly valid in the RFC to not return certain properties that the server deems are too costly to return. In these situations, specific properties can be explicitly requested from the server using this configuration setting.
dav.OnDirList += (obj, ev) => Debug.WriteLine("The creationdate for " + ev.DisplayName + " is " + dav.GetProperty("creationdate"));
dav.Config("QueryPropertyNames=creationdate");
dav.ListDirectory("http://webdav-server.com/DAV/");

The current element is specified through the XPath configuration setting. This configuration setting is read-only.
When XPath is set to a valid path, XElement points to the name of the element, with XText, XParent, XSubTree, XChildCount, XChildName[i], and XChildXText[i] providing other properties of the element.
XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the / character, for example, /A/B/C/D. An XPath can be absolute (i.e., it starts with /), or it can be relative to the current XPath location.
The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors, which proceed it in the overall XPath string:
Accessor | Description |
name | The first element with a particular name. Can be *. |
[i] | The i-th element. |
name[i] | The i-th element with a particular name. |
[last()] | The last element. |
[last()-i] | The element i before the last element. |
name[@attrname="attrvalue"] | The first element with a particular name that contains the specified attribute-value pair.
Supports single and double quotes. (XML Only) |
. | The current element. |
.. | The parent element. |
For example, assume the following XML and JSON responses.
XML:
<firstlevel> <one>value</one> <two> <item>first</item> <item>second</item> </two> <three>value three</three> </firstlevel>
JSON:
{ "firstlevel": { "one": "value", "two": ["first", "second"], "three": "value three" } }
The following are examples of valid XPaths for these responses:
Description | XML XPath | JSON XPath |
Document root | / | /json |
Specific element | /firstlevel/one | /json/firstlevel/one |
i-th child | /firstlevel/two/item[2] | /json/firstlevel/two/[2] |
This list is not exhaustive, but it provides a general idea of the possibilities.

HTTP Config Settings
When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".
The default value is True.
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.
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]".
The default value is False.
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: 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 potentially could change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server or port are different from 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.
Following are the valid options:
- 0 - Never
- 1 - Always
- 2 - Same Scheme
- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"
When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.
HTTP/2 Notes
When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. 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 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.
HTTP/3 Notes
HTTP/3 is supported only in .NET and Java.
When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.
The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:
Sat, 29 Oct 2017 19:43:31 GMT.
The default value for KeepAlive is false.
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are 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).
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .
Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.
This configuration setting is useful for extending the functionality of the class beyond what is provided.
.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"));
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.
The default value is False and the hostname will always be used exactly as specified.
When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.
Override the default with the name and version of your software.
TCPClient Config Settings
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.
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.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.
0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect 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.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if 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 are 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 (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multihomed 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 multihomed hosts (machines with more than one IP interface).
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 configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
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.

Note: This value is not applicable in Java.
By default, this configuration setting is set to False.
0 | IPv4 only |
1 | IPv6 only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
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 configuration setting has no effect if SSLProvider is set to Platform.
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.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
Note: This configuration 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 configuration 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 configuration setting.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

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 SSLProvider is set.
Example values:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");

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.
Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only 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 available only 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, these 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.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
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 SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.
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 traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:

When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration 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:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration 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.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
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 configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only 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_secp384r1" (default)
- "ecdhe_secp521r1"

Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
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.
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 Config Settings
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.
- 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).
- Last Valid Build: The last valid build number for which the license will work.
This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
The Java edition requires installation of the FIPS-certified Bouncy Castle library regardless of the target operating system. This can be downloaded from https://www.bouncycastle.org/fips-java/. Only the "Provider" library is needed. The jar file should then be installed in a JRE search path.
The following classes must be imported in the application in which the component will be used:
import java.security.Security;
import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider;
The Bouncy Castle provider must be added as a valid provider and must also be configured to operate in FIPS mode:
System.setProperty("org.bouncycastle.fips.approved_only","true");
Security.addProvider(new BouncyCastleFipsProvider());
When UseFIPSCompliantAPI is true, Secure Sockets Layer (SSL)-enabled classes can optionally be configured to use the Transport Layer Security (TLS) Bouncy Castle library. When SSLProvider is set to sslpAutomatic (default) or sslpInternal, an internal TLS implementation is used, but all cryptographic operations are offloaded to the Bouncy Castle FIPS provider to achieve FIPS-compliant operation. If SSLProvider is set to sslpPlatform, the Bouncy Castle JSSE will be used in place of the internal TLS implementation.
To enable the use of the Bouncy Castle JSSE take the following steps in addition to the steps above. Both the Bouncy Castle FIPS provider and the Bouncy Castle JSSE must be configured to use the Bouncy Castle TLS library in FIPS mode. Obtain the Bouncy Castle TLS library from https://www.bouncycastle.org/fips-java/. The jar file should then be installed in a JRE search path.
The following classes must be imported in the application in which the component will be used:
import java.security.Security;
import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider;
//required to use BCJSSE when SSLProvider is set to sslpPlatform
import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;
The Bouncy Castle provider must be added as a valid provider and also must be configured to operate in FIPS mode:
System.setProperty("org.bouncycastle.fips.approved_only","true");
Security.addProvider(new BouncyCastleFipsProvider());
//required to use BCJSSE when SSLProvider is set to sslpPlatform
Security.addProvider(new BouncyCastleJsseProvider("fips:BCFIPS"));
//optional - configure logging level of BCJSSE
Logger.getLogger("org.bouncycastle.jsse").setLevel(java.util.logging.Level.OFF);
//configure the class to use BCJSSE
component.setSSLProvider(1); //platform
component.config("UseFIPSCompliantAPI=true");
Note: TLS 1.3 support requires the Bouncy Castle TLS library version 1.0.14 or later.
FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.
For more details, please see the FIPS 140-2 Compliance article.
Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.
Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.
This setting is set to false by default on all platforms.
