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_22.dll component that is compatible with IBM HTTP Server V7.0 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.
