Get-RSS ConfigurationThe cmdlet 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 cmdlet, access to these internal properties is provided through the Config method.
RSS Configuration Settings
Additional data to be added to an RSS Feed item.
This config allows you to specify additional data to be added to an RSS Feed item.
Valid array indices are from 0 to Items.Count - 1.
Note: This config is write-only and no validation is performed on the specified data.
Format of data returned or set.
This config specifies the format of the data set or received into/from XML value
The following are the possible values:
HTTP Configuration Settings
|AcceptEncoding: Used to tell the server which types of content encodings the client supports.When AllowHTTPCompression is true, the cmdlet 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 cmdlet only supports gzip and deflate decompression algorithms.|
This property enables HTTP compression for receiving data.This setting enables HTTP compression for receiving data.
When set to True (default), the cmdlet will accept compressed data. It will then uncompress the data it has received. The cmdlet will handle data compressed by both GZIP and Deflate compression algorithms.
When true, the cmdlet 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.
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 cmdlet will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False the cmdlet throws an exception 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.|
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
This property is provided so that the HTTP cmdlet can be extended with other security schemes in addition to the authorization schemes already implemented by the cmdlet.
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.|
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 cmdlet.If set to True the URL passed to the cmdlet will be URL encoded. The default value is False.|
Determines what happens when the server issues a redirect.This option determines what happens when the server issues a redirect. Normally, the cmdlet 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 cmdlet throws an exception.
Note that following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.
A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g. new authentication parameters).
The default value is 0 (Never). In this case, redirects are never followed, and the cmdlet throws an exception instead.
Valid options are:
|GetOn302Redirect: If set to true the cmdlet will perform a GET on the new location.The default value is false. If set to true the cmdlet 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.|
The version of HTTP used by the cmdlet.This property specifies the HTTP version used by the cmdlet. Possible values are:
When using HTTP/2 ("2.0") additional restrictions apply. Please see notes below for details.
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 cmdlet will automatically use HTTP/1.1 instead. This is done in order to provide compatibility without the need for any additional settings. To see which version was used check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.
HTTP/2 is supported on all versions of Windows. If the Windows version is prior to Windows 8.1/Windows Server 2012 R2 the internal security implementation will be used. If the Windows version is Window 8.1/Windows Server 2012 R2 or later the system security libraries will be used by default.
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.
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.|
The level of detail that is logged.This setting controls the level of detail that is logged through the Log event. Possible values are:
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 cmdlet 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 cmdlet will fallback to using "1.1" automatically. This setting will indicate which was used.|
Other headers as determined by the user (optional).This configuration option can be set to a string of headers to be appended to the HTTP request headers.
The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .
Use this configuration option with caution. If this configuration option contains invalid headers, HTTP requests may fail.
This configuration option is useful for extending the functionality of the cmdlet 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 is the same as ProxyAuthScheme. This setting is provided for use by cmdlets that do not directly expose Proxy properties.|
|ProxyPassword: A password if authentication is to be used for the proxy.This is the same as ProxyPassword. This setting is provided for use by cmdlets that do not directly expose Proxy properties.|
|ProxyPort: Port for the proxy server (default 80).This is the same as ProxyPort. This setting is provided for use by cmdlets that do not directly expose Proxy properties.|
|ProxyServer: Name or IP address of a proxy server (optional).This is the same as ProxyServer. This setting is provided for use by cmdlets that do not directly expose Proxy properties.|
|ProxyUser: A user name if authentication is to be used for the proxy.This is the same as ProxyUser. This setting is provided for use by cmdlets 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 cmdlet.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 cmdlet.|
|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.|
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.
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"));
Enables or Disables HTTP chunked encoding for transfers.
If UseChunkedEncoding is set to true, the cmdlet 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 cmdlet 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.
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.
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 cmdlet will use Timeout for establishing a connection and transmitting/receiving data.|
|FirewallAutoDetect: Tells the cmdlet whether or not to automatically detect and use firewall system settings, if available.This is the same as FirewallAutoDetect. This setting is provided for use by cmdlets that do not directly expose Firewall properties.|
Name or IP address of firewall (optional).If a FirewallHost is given, requested connections will be authenticated through the specified firewall
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 is the same as FirewallHost. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
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 cmdlet throws an exception.
NOTE: This is the same as FirewallPassword. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
The TCP port for the FirewallHost;.Note that the FirewallPort is set automatically when FirewallType is set to a valid value.
NOTE: This is the same as FirewallPort. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
Determines the type of firewall to connect through.The appropriate values are as follows:
NOTE: This is the same as FirewallFirewallType. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
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 cmdlet throws an exception.
NOTE: This is the same as FirewallUser. This setting is provided for use by cmdlets that do not directly expose Firewall properties.
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 Java or MAC.
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.
Note: This value is not applicable in Java.
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 cmdlet 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.|
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 cmdlet initiate connections (or accept in the case of server cmdlets) only through that interface.
If the cmdlet 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).
The port in the local host where the cmdlet binds.
This must be set before a connection is
attempted. It instructs the cmdlet 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.
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
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.|
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:
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.
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.
Whether to use IPv6.When set to 0 (default), the cmdlet will use IPv4 exclusively.
When set to 1, the cmdlet will use IPv6 exclusively. To instruct the cmdlet 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:
Socket Configuration Settings
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).|
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 cmdlet is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
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 cmdlet is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Base Configuration Settings
|BuildInfo: Information about the product's build.When queried, this setting will return a string containing information about the product's build.|
The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).
The following is a list of valid code page identifiers:
Information about the current license.When queried, this setting will return a string containing information about the license this instance of a cmdlet is using. It will return the following information:
Tells the cmdlet whether or not to use the system security libraries or an internal implementation.
By default the cmdlet will use the system security libraries to perform cryptographic functions.
When set to False calls to unmanaged code will be made. In certain environments this is not desirable.
To use a completely managed security implementation set this setting to True.
Setting this to True tells the cmdlet to use the internal implementation
instead of using the system's security API.
Note: This setting is static. The value set is applicable to all cmdlets used in the application.
When this value is set the product's system DLL is no longer required as a reference, as all unmanaged code is stored in that file.
