EAServer 4.0 includes a servlet response cache to improve response times for Web clients. When page caching is enabled for a servlet or JSP, EAServer checks the cache before invoking the servlet. If an appropriate response is found in the cache, EAServer returns the contents of the cache, instead of calling the servlet. If a response is not found in the cache, EAServer invokes the servlet, then saves the response and the response headers in the cache.
Servlet response caching can be enabled and configured in EAServer Manager. No programming is required. For more information, see Chapter 5, “Web Application Tuning,” in the EAServer Performance and Tuning Guide.
