Abstract

System and method for caching JavaServer Page.TM. (JSP) component responses. The JSP components may be components that execute on an application server that supports networked applications, such as web applications or other Internet-based applications. One or more client computers, e.g., web servers, may perform requests referencing the JSP components on the application server. The execution of JSP components may be managed by a JSP engine process running on the application server. When a request referencing a JSP is received from a client computer, the JSP engine may first check a JSP response cache to determine whether a valid JSP response satisfying the request is present. If a matching cached response is found, then the response may be retrieved and immediately streamed back to the client. Otherwise, the referenced JSP may be executed. Each JSP file may comprise various SetCacheCriteria( ) method calls. When executed, the SetCacheCriteria( ) call may cause the output of the JSP to be cached once the JSP execution is complete. Arguments to the SetCacheCriteria( ) call may specify a criteria set that should be associated with the cached JSP response. This criteria set may then be used to match against attributes of future JSP requests, as described above. In particular embodiments, any of various types of cache criteria may be supported.
