Atom Control

Properties   Methods   Events   Configuration Settings   Errors  

The Atom Control is used to retrieve, parse, and update Atom content.

Syntax

Atom

Remarks

The Atom control 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 Atom Control implements a standard Atom client as defined by RFC 4287 (http://www.ietf.org/rfc/rfc4287) and includes the Atom publishing capabilities as defined by the "The Atom Publishing Protocol" (http://www.ietf.org/rfc/rfc5023).

The control contains a number of properties that map directly to Atom fields. To receive a feed, call the GetFeed method with the URL or file to retrieve specified in the URL parameter. You may also update the Entries properties using the Put method.

The Atom Control supports all standard Atom properties and allows you to add your own through AddNamespace and the GetProperty and SetProperty methods.

Accept Property (Atom Control)

A list of acceptable MIME types for the request.

Syntax

atomcontrol.Accept[=string]

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.

Data Type

String

AtomData Property (Atom Control)

This is the complete content of the Atom resource.

Syntax

atomcontrol.AtomData[=string]

Default Value

""

Remarks

This property will contain the bytes received when retrieving Atom feeds or a media type through the GetResource method. When writing an Atom feed using the WriteFile method, the AtomData will be generated from the existing properties.

To read or write binary data to the property, a Variant (Byte Array) version is provided in .AtomDataB.

This property is not available at design time.

Data Type

Binary String

Authorization Property (Atom Control)

The Authorization string to be sent to the server.

Syntax

atomcontrol.Authorization[=string]

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 control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

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]".

Data Type

String

AuthScheme Property (Atom Control)

The authentication scheme to use when server authorization is required.

Syntax

atomcontrol.AuthScheme[=integer]

Possible Values

  authBasic(0), 

  authDigest(1), 

  authProprietary(2), 

  authNone(3), 

  authNtlm(4), 

  authNegotiate(5), 

  authOAuth(6)

Default Value

0

Remarks

This property will tell the control 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 control 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 control to clear the values of User, Password and Authorization.

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the control 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 control fails with an error.

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 control fails with an error instead.

Remarks

This property is used to tell the control which type of authorization to perform when connecting to the proxy. This is only used when the ProxyUser and ProxyPassword properties are set.

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

By default, ProxyAuthScheme is authBasic (0), and if the ProxyUser and ProxyPassword properties are set, the component will attempt basic authentication.

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

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

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

For security reasons, setting this property will clear the values of ProxyUser and ProxyPassword.

Remarks

When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.

GetFeed Method (Atom Control)

This method fetches an Atom feed.

Syntax

atomcontrol.GetFeed URL

Remarks

This method fetches the document. The document contents are delivered in the AtomData property, as well as through the Transfer event, and the HTTP response headers through the Header event.

Then the control will attempt to parse the Atom feed, filling in the Channel and Entries properties as it goes. The Channel properties also can be accessed using the GetProperty and SetProperty methods, if necessary.

GetProperty Method (Atom Control)

This method fetches the value of a specific Atom feed element or attribute.

Syntax

atomcontrol.GetProperty PropertyName

Remarks

This method is intended for extending functionality of the Atom control. It will fetch the value for a specific entry element or attribute of this Atom feed. Property is the XPath of the element or attribute according to the following convention: /feed/element@attribute or entry[x]/element@attribute. The @attribute part is optional.

entry[x] is the Channel's xth entry (or any other root-level child), where the indexer x starts at 1.

element is any child of the Channel or an entry, and attribute can be any attribute of that field. If an attribute is not supplied, the GetProperty method will return the text portion of element. For example:

AtomControl.GetProperty("entry[5]/link@href") AtomControl.GetProperty("entry[5]/author/name") AtomControl.GetProperty("/feed/title")

Note: To add nonstandard fields (i.e., fields that are not defined in the Atom specification), element must be prefixed with a namespace that defines that field. The same applies for the attribute field. Use the Namespaces properties to define and list namespaces.

GetResource Method (Atom Control)

This method fetches a resource.

Syntax

atomcontrol.GetResource URL

Remarks

This method fetches the resource. If LocalFile is set, the document will be saved in the specified file. Otherwise, the document contents are delivered in the AtomData property, as well as through the Transfer event, and the HTTP response headers are delivered through the Header event.

Unlike the GetFeed method, after retrieval, the control will not attempt to parse the data into the Channel and Entries properties.

Interrupt Method (Atom Control)

Interrupt the current method.

Syntax

atomcontrol.Interrupt 

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

PostResource Method (Atom Control)

This method posts a resource to the specified URL.

Syntax

atomcontrol.PostResource URL

Remarks

This method will post a resource to the specified URL. It will either post a media resource if UpdateFile is specified or an Atom entry if UpdateEntry is specified. UpdateFile takes precedence over UpdateEntry.

Put Method (Atom Control)

This method sends data to the HTTP server using the HTTP PUT method.

Syntax

atomcontrol.Put URL

Remarks

This method will put a resource to the specified URL. It will either put a media resource if UpdateFile is specified or an Atom entry if UpdateEntry is specified. UpdateFile takes precedence over UpdateEntry.

PutResource Method (Atom Control)

This method puts a resource to the specified URL.

Syntax

atomcontrol.PutResource URL

Remarks

This method will put a resource to the specified URL. It will either put a media resource if UpdateFile is specified or an Atom entry if UpdateEntry is specified. UpdateFile takes precedence over UpdateEntry.

ReadFile Method (Atom Control)

This method loads an Atom file into the control.

Syntax

atomcontrol.ReadFile FileName

Remarks

This method loads an Atom file and attempts to parse it, filling in the Channel and Entries properties as it goes. The Channel properties also can be accessed using the GetProperty and SetProperty methods if necessary.

Reset Method (Atom Control)

This method resets all properties of the control.

Syntax

atomcontrol.Reset 

Remarks

This method resets all properties to the control's default settings. This is an easy way to clear all of the property values before repopulating the Atom feed.

SetProperty Method (Atom Control)

This method sets the value of a specific Atom feed property.

Syntax

atomcontrol.SetProperty PropertyName, PropertyValue

Remarks

This method is intended for extending functionality of the Atom control. It will set the value for a specific field of this Atom feed. Property is the name of the property according to the following convention: root/element@attribute. The root field can be either of the two following values:

feedThis treats the channel as the root level, and element is any property of the channel. If an empty string ("") is supplied for the root field, the control will assume the channel is the root.
entry[x]This treats the channel's x-th entry as the root level. The field element is any property of an entry.

The element field can be any property of the root field, and attribute can be any property of that field. If an attribute is not supplied, Value will be placed in the text portion of element. For example:

AtomControl.SetProperty("entry[5]/link@type", "text/html")

Note: To add nonstandard fields (i.e., fields that are not defined in the Atom specification), element must be prefixed with a Namespace that defines that field. The same applies for the attribute field. Use the Namespaces properties to define and list Namespaces.

WriteFile Method (Atom Control)

This method is used to write an Atom feed from the control.

Syntax

atomcontrol.WriteFile Filename

Remarks

This method will write an Atom feed from the existing property values to Filename. The Atom feed will be pre-verified, and if any missing required fields are encountered, the control fails with an error.

Example (Add an Item and Write)

AtomControl.EntryCount = 1 AtomControl.EntryContent(0) = "New Item Description" AtomControl.EntryLinkHref(0) = "http://itemurl" AtomControl.WriteFile(filename)

Connected Event (Atom Control)

Fired immediately after a connection completes (or fails).

Syntax

Sub atomcontrol_Connected(StatusCode As Integer, Description As String)

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 TCP/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

ConnectionStatus Event (Atom Control)

Fired to indicate changes in connection state.

Syntax

Sub atomcontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)

Remarks

The ConnectionStatus event is fired when the connection state changes: completion of a firewall or proxy connection, completion of a security handshake, etc.

The ConnectionEvent parameter indicates the type of connection event. Values may include:

Firewall connection complete.
SSL or S/Shell handshake complete (where applicable).
Remote host connection complete.
Remote host disconnected.
SSL or S/Shell connection broken.
Firewall host disconnected.

StatusCode has the error code returned by the TCP/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Disconnected Event (Atom Control)

Fired when a connection is closed.

Syntax

Sub atomcontrol_Disconnected(StatusCode As Integer, Description As String)

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 TCP/IP subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

EndTransfer Event (Atom Control)

This event fires when a document finishes transferring.

Syntax

Sub atomcontrol_EndTransfer(Direction As Integer)

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

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

Error Event (Atom Control)

Information about errors during data delivery.

Syntax

Sub atomcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

ErrorCode contains an error code and Description 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 (Atom Control)

Fired every time a header line comes in.

Syntax

Sub atomcontrol_Header(Field As String, Value As String)

Remarks

The Field parameter contains the name of the HTTP header (same case as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (Atom Control)

Fires once for each log message.

Syntax

Sub atomcontrol_Log(LogLevel As Integer, Message As String, LogType As String)

Remarks

This event fires once for each log message generated by the control. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. 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).

Message is the log entry.

LogType identifies the type of log entry. Possible values are:

  • "Info"
  • "RequestHeaders"
  • "ResponseHeaders"
  • "RequestBody"
  • "ResponseBody"
  • "ProxyRequest"
  • "ProxyResponse"
  • "FirewallRequest"
  • "FirewallResponse"

Redirect Event (Atom Control)

Fired when a redirection is received from the server.

Syntax

Sub atomcontrol_Redirect(Location As String, Accept As Boolean)

Remarks

This event is where the client can decide whether to continue with the redirection process or not. 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 control fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.

SetCookie Event (Atom Control)

Fired for every cookie set by the server.

Syntax

Sub atomcontrol_SetCookie(Name As String, Value As String, Expires As String, Domain As String, Path As String, Secure As Boolean)

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 through a secure (HTTPS) connection only.

SSLServerAuthentication Event (Atom Control)

Fired after the server presents its certificate to the client.

Syntax

Sub atomcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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 (Atom Control)

Shows the progress of the secure connection.

Syntax

Sub atomcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

StartTransfer Event (Atom Control)

This event fires when a document starts transferring (after the headers).

Syntax

Sub atomcontrol_StartTransfer(Direction As Integer)

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

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

Status Event (Atom Control)

Fired when the HTTP status line is received from the server.

Syntax

Sub atomcontrol_Status(HTTPVersion As String, StatusCode As Integer, Description As String)

Remarks

HTTPVersion is a string containing the HTTP version string as returned from the server (e.g. "1.1").

StatusCode contains the HTTP status code (e.g. 200), and Description the associated message returned by the server (e.g. "OK").

Transfer Event (Atom Control)

Fired while a document transfers (delivers document).

Syntax

Sub atomcontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)

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.

Configuration Settings (Atom Control)

The control 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 control, access to these internal properties is provided through the Config method.

HTTP Configuration Settings

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

When AllowHTTPCompression is true, the control 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 control 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 control will accept compressed data. It will then uncompress the data it has received. The control will handle data compressed by both GZIP and Deflate compression algorithms.

When true, the control 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 control will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False the control fails with an error if the server does not support HTTP/2.

The default value is True.

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 control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

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 control.

If set to True the URL passed to the control 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 control 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 control fails with an error.

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 control fails with an error instead.

Valid options are:

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

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

The default value is false. If set to true the control 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 control.

This property specifies the HTTP version used by the control. 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 control 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 Windows 8.1/Server 2012 R2 or later. If HTTP/2 is used on a version of Windows prior to these versions the control fails with an error.

Note: HTTP/2 is currently only supported on Windows.

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).

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

When FollowRedirects is set to any value besides frNever the control 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 control 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 (Chr$(13) & Chr$(10)) .

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 control 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 ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme.

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

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

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

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

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

This setting is provided for use by controls 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 controls 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 control.

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 control.

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 control 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 control 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. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance to specify UTF-8 set CodePage to 65001.

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

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 control will use Timeout for establishing a connection and transmitting/receiving data.

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

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

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 control fails with an error.

NOTE: This setting is provided for use by controls 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 controls 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 controls 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 control fails with an error.

NOTE: This setting is provided for use by controls 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 control 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 control initiate connections (or accept in the case of server controls) only through that interface.

If the control 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 control binds.

This must be set before a connection is attempted. It instructs the control 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 control will use IPv4 exclusively. When set to 1, the control will use IPv6 exclusively. To instruct the control 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

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.

OpenSSLCADir:   The path to a directory containing CA certificates.

This functionality is available only when the provider is OpenSSL.

The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCAFile:   Name of the file containing the list of CA's trusted by your application.

This functionality is available only when the provider is OpenSSL.

The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by

-----BEGIN CERTIFICATE-----

... (CA certificate in base64 encoding) ...

-----END CERTIFICATE-----

sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.

OpenSSLCipherList:   A string that controls the ciphers to be used by SSL.

This functionality is available only when the provider is OpenSSL.

The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".

OpenSSLPrngSeedData:   The data to seed the pseudo random number generator (PRNG).

This functionality is available only when the provider is OpenSSL.

By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the control 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 control 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

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

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

This setting specifies whether the control will check the Certificate Revocation List specified by the server certificate. If set to the control will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The control 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 control fails with an error.

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

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.

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 control 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.

Example values when UseInternalSecurityAPI is False (default): obj.config("SSLEnabledCipherSuites=*"); obj.config("SSLEnabledCipherSuites=CALG_AES_256"); obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES"); 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 by default, but can be set to to disable the extension.

This setting is only applicable when UseInternalSecurityAPI is set to .

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.

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 control 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 control 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.

Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed .

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available when the provider is OpenSSL.

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

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

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 control 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 control fails with an error.

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_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)

  • "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 control 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 control 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
