Use the dynamic cache to improve application performance by caching the output of servlets, commands, and JavaServer Pages (JSP) files.
Before you begin
On distributed platforms, WebSphere Application Server, Version 4.0, supported the configuration of dynamic servlet caching through the servletcache.xml file. To utilize the new and improved functionality of the dynamic cache service, configure your cache policy using the cachespec.xml format. See Configuring cacheable objects with the cachespec.xml file for more information.
Why and when to perform this task
The dynamic cache service works within an application server Java virtual machine (JVM), intercepting calls to cacheable objects. For example, it intercepts calls through a servlet service method or a command execute method, and either stores the output of the object to the cache or serves the content of the object from the dynamic cache.Steps for this task
