Web server plug-in request routing properties

View or change the request routing properties for a web server plug-in.

From the admin console, click...

        Servers > Server Types > Web servers > web_server > Plug-in properties > Request routing.

Load balancing option

Load balancing option that the plug-in uses in sending requests to the various application servers associated with that web server.

This field corresponds to the LoadBalance element in the plugin-cfg.xml file.

Select the appropriate load balancing option:

• Round robin
• Random

The Round Robin implementation has a random starting point. The first application server is picked randomly. Round Robin is then used to pick application servers from that point forward. This implementation ensures that in multiple process based web servers, all of the processes don't start up by sending the first request to the same Application Server.

The default load balancing type is Round Robin.

Retry interval

Length of time, in seconds, that should elapse from the time an application server is marked down to the time that the plug-in retries a connection.

This field corresponds to the RetryInterval element in the plugin-cfg.xml file.

Information	Value
Data type	Integer
Default	60 seconds

Maximum size of request content

Select whether there is a limit on the size of request content. If limited, this field also specifies the maximum number of kilobytes of data a request can contain. When a limit is set, the plug-in fails any request that is received containing more data than the specified limit.

This field corresponds to the PostSizeLimit element in the plugin-cfg.xml file.

Select whether to limit the size of request content:

• No limit

• Set limit

If we select Set limit, specify a limit size.

Information	Value
Data type	Integer Specify the size in kilobytes (1024 byte blocks).
Default	-1, which indicates there is no limit for the post size.

Maximum buffer size used when reading HTTP request content

Specifies, in kilobytes, the maximum buffer size used when the content of an HTTP request is read. If the application server that initially receives a request cannot process that request, the data contained in this buffer is sent to another application server in an attempt to have that application server process the request.

This field corresponds to the PostBufferSize element in the plugin-cfg.xml file.

If Set limit is selected, specify a limit size.

Information	Value
Data type	Integer Specify the size in kilobytes (1024 byte blocks).
Default	0 For transitioning users: Beginning with version 8.5, the default value is 0.trns

Remove special headers

When checked, the plug-in will remove any headers from incoming requests before adding the headers the plug-in is supposed to add before forwarding the request to an application server.

This field corresponds to the RemoveSpecialHeaders element in the plugin-cfg.xml file.

The plug-in adds special headers to the request before it is forwarded to the application server. These headers store information about the request that will need to be used by the application. Not removing the headers from incoming requests introduces a potential security exposure.

By default, the special headers are not retained. Clear the check box to retain special headers.

Clone separator change

When this option is selected, the plug-in expects the plus character (+) as the clone separator.

This field corresponds to the ServerCloneID element in the plugin-cfg.xml file.

Some pervasive devices cannot handle the colon character (:) used to separate clone IDs in conjunction with session affinity. If this field is checked, we must also change the configurations of the associated application servers such that the application servers separates clone IDs with the plus character as well.

By default, this option is selected. Clear the field to use the colon character to separate clone IDs.
