This paper introduces a new system of Web Cache. In this system, we introduce the policy that the dynamic content and the static content can deal with separately. Through this policy, we can not only realize caching the dynamic data, but also we can abbreviate the Web Cache's response time. We embed a computational layer named Cache Administrator between the Cache and the Server. Through this embed layer, we realize the function that separate the dynamic content and the static content. This system has good expansibility. It also solve several problems including data consistency, cache cooperation, prefetching, data replacement.
