Abstract
A system and method for facilitating the invalidation of cached data, in which the data to be invalidated are identified using information other than a primary key. The primary key for a cached data object, such as a web page, may be a Uniform Resource Locator (URL). Instead of using an object's URL to identify to a cache the data to be invalidated, a secondary key is used, such as the object's data source or a template from which the object was created. An application communicates the secondary key to a cache, and the cache identifies cached objects that match the secondary key. Those data objects are then invalidated without having to issue multiple invalidation messages from the application.
