Fast Response Cache Accelerator operational restrictions

This section discusses the operational restrictions for the fast response cache accelerator (FRCA). FRCA is also known as Adaptive Fast Path Architecture (AFPA).

The following operational restrictions apply:

Due to these operational restrictions, and since FRCA/AFPA was deprecated starting in V7.0, its use is discouraged. Instead, it is recommended to use the IBM HTTP Server default configuration to serve static files. This configuration provides support for features not available with FRCA/AFPA usage, such as IPv6, SSL, Authentication and access-control, custom headers and compression.

If CPU usage with the default configuration is too high, the mod_mem_cache module can be configured to cache frequently accessed files in memory, or multiple web servers can be used to scale out horizontally. Additional options include the offloading of static files to a Content Delivery Network (CDN) or caching HTTP appliance, or to use the caching proxy component of WebSphere® Edge Server in WebSphere Application Server Network Deployment (ND).
