Experiments Related Work Web caching is an active research area.
Our study does not address caching algorithms or cache consistency maintanence, but overlaps some of client traffic studies in our investigation of the benefits of Web cache sharing. Recently, there have been a number of new cache sharing approaches proposed in the literature. An advantage of the approach is that it eliminates duplicate copies of documents. However, it is not clear how well the approach performs for wide-area cache sharing, where proxies are distributed over a regional network. The idea is similar to summary cache.
