The World Wide Web suffers from scaling and reliability problems due to overloaded and congested proxy servers. Caching at local proxy serves help, but cannot satisfy more than a third to half of requests; more requests are still sent to original remote servers. In this paper we have developed an algorithm for Distributed Web Cache, which incorporates cooperation among proxy servers of one cluster. This algorithm uses Distributed Web Cache concepts along with static hierarchies with geographical based clusters of level one proxy server with dynamic mechanism of proxy server during the congestion of one cluster. Congestion and scalability problems are being dealt by clustering concept used in our approach. This results in higher ratio of caches, with lesser latency delay for requested pages. This algorithm alsi guarantees data consistency between the original server objects and the proxy cache objects.
