The dynamic cache can control caches outside of the application
server, such as the Edge server, an IBM HTTP Server, or an HTTP Server ESI
Fragment Processor plug-in.
About this task
When external cache groups are defined, the dynamic cache matches
externally cacheable cache entries with those groups, and pushes cache entries
and invalidations out to those groups. This allows WebSphere Application Server
to manage dynamic content beyond the application server. The content can then
be served from the external cache, instead of the application server, improving
savings in performance.
