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.
