You can use the fast response cache accelerator (FRCA) with WebSphere Application Server to cache certain dynamically-generated servlet and JavaServer Pages (JSP) files. This feature is only available on Windows versions of IBM HTTP Server.
Enable IBM HTTP Server for dynamic page caching by enabling the cache accelerator. In addition, the afpaplugin_20.dll component that is compatible with IBM HTTP Server V6.1 must be configured by WebSphere Application Server.
For details on how to enable this capability, see Configuring high-speed external caching through the Web server in the WebSphere Application Server product documentation.
