Abstract
The present invention provides a method, system, and computer program product for selectively replacing cached content (including, but not limited to, dynamically generated Web pages which have been cached) to provide a higher level of service to particular users or groups of users. Service providers may use the disclosed techniques to justify charging for an enhanced quality of service. The disclosed techniques enable reducing, in many cases, the system overhead and response time required for delivering content to those content requesters who have this type of enhanced service. When content is evaluated for potential caching and the cache is determined to be full, content is selected for overwriting according to the quality of service level of the content owner.
