Site-Based Approach to Web Cache Design

A site-based approach to Web caching tracks documents by site rather than individual document names or URLs, bringing different benefits to several different types of applications. One problem, however, is that while maintaining only site information is sufficient in many cases, it is sometimes necessary to track individual documents. For example, although the site-based least-recently-used (LRU) purging purges a whole site when a cache replacement is required, the system might still need information on individual cached documents. Currently, we are attempting to modify a real proxy server to use the site-based approach.
