%X A new cooperative Web caching system (CHRCS) based on consistent hashing function was proposed. Aiming at reducing the multilevel latency in traditional cooperative Web caching systems, a efficient location and routing schema of Web objects was designed,through which a Web request can reach the target cache by only one hash computation and through less than one transfer. The strategy of invalidation-triggering was assumed to solve the problem of routing consistency, which reduced network traffic and made system more robust and scalable. Simulation results show that the performance of CHRCS is much better than that of systems of Internet cache protocol(ICP) and cache array routing protocol(CARP).
