A Web caching infrastructure is built using groups of HTTP proxy servers that share cached objects. This paper describes an architecture that takes the best of several Web caching configurations that we have previously analyzed. The flexibility of our architecture is demonstrated and how the access to remote Web objects is improved regardless of the changes that might occur on the network environment (which in term, might cause changes in Web object validation policies and types of caching communication). We have seen that some cooperative Web caching architectures are unviable when changes on the network environment appear. These changes give, as a result a degradation of performance in the remote access. The situation mentioned suggests that the use of a cooperative Web caching system is unviable. We demonstrated that with our architecture we have a Web cache system that remains viable even if some changes are needed in the Web cache configuration.
