HTTP transport channel custom properties

For an HTTP transport channel, we can add any of the following custom properties to the settings for that channel.

To add a custom property:

1. In the admin console ...

   Servers > Server Types, and then select one of the following options, depending on the type of chain we are creating:

   • Application servers > server_name, and then, under Web Container Settings, click Web container transport chains > chain_name > HTTP Inbound Channel > Custom Properties > New.
   • Proxy servers, and then, under HTTP Proxy Server Settings, click Proxy server transports. Then, select either HTTPS_PROXY_CHAIN or HTTP_PROXY_CHAIN , and then click > HTTP Inbound Channel > Custom Properties > New .

2. Under General Properties specify the name of the custom property in the Name field and a value for this property in the Value field. We can also specify a description of this property in the Description field.

3. Click Apply or OK.

4. Click Save to save the configuration changes.

5. Restart the server.

Following are the descriptions of the HTTP transport channel custom properties provided with WAS ND. These properties are not shown on the settings page for an HTTP transport channel.

CookiesConfigureNoCache

Use the CookiesConfigureNoCache property to specify whether the presence of a Set-Cookie header in an HTTP response message triggers the addition of several cache related headers. If this property is set to true, an Expires header with a very old date, and a Cache-Control header that explicitly tells the client not to cache the Set-Cookie header are automatically added. These headers are not automatically added if this property is set to false.

Is functionality equivalent to the com.ibm.websphere.cookies.no.header property that was available in previous versions of WAS ND.

Data type	Boolean
Default	True

localLogFilenamePrefix

Use the localLogFilenamePrefix property to specify a prefix for the filename of the network log file. Normally, when inprocess optimization is enabled, requests through the inprocess path are logged based on the logging attributes set up for the Web container's network channel chain. Use this property to add a prefix to the filename of the network log file. This new filename is then used as the filename for the log file for inprocess requests. Requests sent through the inprocess path are logged to this file instead of to the network log file. For example, if the log file for a network transport chain is named .../httpaccess.log, and this property is set to local for the HTTP channel in that chain, the filename of the log file for inprocess requests to the host associated with that chain is …/localhttpaccess.log.

Avoid trouble: If we specify a value for the localLogFilenamePrefix custom property, also set the accessLogFileName HTTP channel custom property to the fully qualified name of the log file you want to use for in process requests. We cannot specify a variable, such as $(SERVER_LOG_ROOT), as the value for this custom property.

Data type

String

limitFieldSize

Use the limitFieldSize property to enforce the size limits on various HTTP fields, such as request URLs, or individual header names or values. Enforcing the size limits of these fields guards against possible Denial of Service attacks. An error is returned to the remote client if a field exceeds the allowed size.

Data type	Integer
Default	32768
Range	50-32768

limitNumHeaders

Use the limitNumHeaders property to limit the number of HTTP headers that can be present in an incoming message. If this limit is exceeded, an error is returned to the client.

Data type	Integer
Default	500
Range	50 to 500

RemoveServerHeader

Use the RemoveServerHeader property to force the removal of any server header from HTTP responses that the appserver sends, thereby hiding the identity of the server program.

Data type	Boolean
Default	False

ServerHeaderValue

Use the ServerHeaderValue property to specify a header that is added to all outgoing HTTP responses if a server header does not already exist.

Data type	String
Default	WAS v/x.x, where x.x is the version of WAS that is running on the system.
