Configure external caching

The dynamic cache service has the ability to control caches outside of the application server, such as IBM Edge Server's cache and IBM HTTP Server's cache (Fast Response Cache Accelerator, or FRCA). When you define external cache groups, the dynamic cache service matches externally cacheable cache entries with those groups and pushes cache entries and invalidations out to those groups. This allows WAS to manage dynamic content beyond the application server. The content can be served from the external cache instead of the application server, which can improve performance.

Use the following steps to configure external caching:

• Configure Edge Server Include processor caching
  This topic describes how to configure the Edge Server Include processor through the WAS's Web server plug-in configuration file, plugin-cfg.xml.

• Configure an external cache group on the application server
  This topic describes how to configure an external cache group using WAS administrative console.

• Configure high-speed external caching through the Web server
  This topic describes how to configure IBM HTTP Server's high speed cache, the Fast Response Cache Accelerator (FRCA). WAS fragment cache can use IBM HTTP Server as an external cache with the appropriate configuration.
