Summary form only given. Web caching is the most important technique to reduce network bandwidth consumption and minimize user-perceived latency. However, most researches are focused on designing efficient architectures with dedicated proxy servers, the potential advantage of utilizing client cache is not fully exploited. We propose a new solution to improve Web caching performance using local cache on client computers. Our system has several advantages than the dedicated proxy server mechanism. First, a larger virtual cache is generated to cache more documents than a single proxy server. Second, it is scalable, system workloads are distributed all across client computers instead of concentrated on a central server, the "hot spot" and "single point of failure " problems are relieved. Third, by the introduction of the superclients, the effect of the weak clients in a fully decentralized scheme is also alleviated. The simulation results show our system can achieve better system caching performance and scalability than the previous solutions.
