A Survey of World Wide Web Caching

Academic and corporate communities have been dedicating considerable eeort to World Wide Web caching, When correctly deployed, Web caching systems can lead to significant bandwidth savings, server load balancing, perceived network latency reduction, and higher content availability. In this paper, we survey state-of-the-art caching designs and implementations. We present a taxonomy of architec-tures and describe some of their design techniques. Finally, we summarize a number of existing commercial and academic systems.
