Why and when to perform this task
See Web server plug-in policy for WebSphere Application Server for information about how to verify what V4.0, V5.0, V5.1 and V6.0 plug-in versions are installed on local or remote Web servers, and how to determine if the installation complies with supported configurations.
Web server plug-ins are included with the WebSphere Application Server for z/OS product. These plug-in can be used to forward requests for Web applications from a supported Web server to a WebSphere Application Server for z/OS Web container. A WebSphere Application Server Configuring transports provides the connection between the Web server plug-in and the Web container.
In a WebSphere Application Server for z/OS environment, it is faster to directly use the HTTP transport than to configure Web server plug-ins. However, you might want to use the Web server plug-ins if you are looking for easier configuration of new application servers or applications within a cluster.
To configure a Web server plug-in:
Steps for this task
Ensure that Web servers are configured to perform operations required by Web applications, such as GET and POST. Typically, this involves setting a directive in the Web server configuration file (such as httpd.conf for IBM HTTP Server). Refer to the Web server documentation for instructions. If an operation is not enabled when a servlet or JSP file requiring the operation is accessed, an error message displays, such as this one from IBM HTTP Server:
IMW0093E Method POST is disabled on this server
