A dynamic content caching framework that encodes dynamically created documents with a filename that is derived from the state information describing the contents of the document, advantageously allows for the dynamically created documents to be cached and reused, thereby reducing server computation, and allowing more users to utilize a particular web site. A file cache management system manages files that can be provided by a web server computer system to a client computer system. Parameters selected by a user viewing a web page define a presentation state that describes, and is used to produce, a subsequent web page. The presentation state is processed using a one-way hashing function to form a hash value, or signature, for that presentation state which is then used to identify the file in which presentation information for the presentation state is stored. When another user chooses the same presentation state, the existing file having presentation information can be identified quickly and reused.
