document: A unifying co-operative Web caching architecture Network caching of objects has become a standard way of reducing network traffic and latency in the Web . However , Web caches exhibit poor performance with a hit rate of about 30 % . A solution to improve this hit rate is to have a group of proxies form co-operation where objects can be cached for later retrieval . A cooperative cache system includes protocols for hierarchical and transversal caching . The drawback of such a system lies in the resulting network load due to the number of messages that need to be exchanged to locate an object . This paper proposes a new co-operative Web caching architecture , which unifies previous methods of Web caching . Performance results shows that the architecture achieve up to 70 % co-operative hit rate and accesses the cached object in at most two hops . Moreover , the architecture is scalable with low traffic and database overhead
