Abstract:

As the size of the World Wide Web increases at a rate much higher than that of adding networking infrastructure, the perceived latency of the Web becomes an important issue. This report surveys the research done in the past few years on web caching, which is one of the techniques that attempts to keep low the traffic on the Web. After introducing the problem and the general idea of how to solve it, the report will concentrate on different issues related to caching: its advantages and disadvantages, caching policies that can be used. The report then discusses in detail about maintaining a cache which also covers coherence checks. Using web caching systems one can alleviate much load on the web and provide better content availability.
