Modifying web server plug-in properties from the WebSphere Application Server administrative console

Question

How can I modify the web server's plug-in (plugin-cfg.xml) properties from the WebSphere Application Server administrative console?

Cause

You are unable to determine where to make web server plug-in changes from the WebSphere Application Server administrative console.

Answer

IBM recommends that modifications to the web server plug-in properties be made from the WebSphere Application Server administrative console so any changes are persisted when a newplugin-cfg.xml file is generated and propagated to the web server.

The following information is provided as a guide to assist you in determining where to make specific plug-in property changes from the WebSphere Application Server administrative console.

• Plug-in properties
• Plug-in properties > Request and response
• Plug-in properties > Caching
• Plug-in properties > Request routing
• cluster_member_name > Web server plug-in properties
• cluster_name > Cluster members
• cluster_member_name > Session management
• application_name > Session management
• Web server plug-in custom properties
• Additional resources
