摘要：These days, the web has grown tremendously to fulfill the requests from huge number of users. Caching strategies are applied to minimize the retrieval latency of objects by a user. The contents are replicated using proxy servers closer to the users to reduce the network distance between the object and the user. In this paper, a study has been presented for the evaluation of several caching schemes and their issues. At the end, it has been observed that cache cooperation can improve the performance at a larger scale. The cache cooperation at each level of hierarchy also minimizes the client's retrieval latency. The paper also discusses some approaches to manage Scalability & Metadata Server, extra overhead at overloaded proxy servers by introducing dynamic functionality in distributed web caching
