Web server plug-in request routing properties settings
Use this page to view or change the request routing properties for a web server plug-in.
To view this administrative console page, click web_server_name.
Load balancing option
Specifies the 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.
- 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
Specifies the 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 that contains more data than the specified limit.
This field corresponds to the PostSizeLimit element in the plugin-cfg.xml file.
- No limit
- Set limit
If you 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 that is 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.

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, you 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 if you want to use the colon character to separate clone IDs.
