Abstract
The invention provides a system and method for providing response caching and filtering for servlets, and particularly for allowing a developer to specify a cache filter for use in caching servlet pages. The cache filter caches on a page level (or included page) instead of at a JSP fragment level. Also, instead of declaring the caching parameters inside the Web document itself, a developer can declare the parameters in the configuration of the web application. The result is that server load is greatly reduced in situations involving many users and frequently changing data. The ability to administer the cache parameters directly instead of at a proxy gives the developer greater latitude in administering and optimizing the performance of their e-commerce application.
