Web Caching: A Survey

Abstract

World Wide Web traffic increases at exponential rates saturating network links and web servers. By replicating popular web pages in strategic places on the Internet, web caching reduces core network traffic, reduces web server load, and improves the end-users’ perceived quality of service. In this paper we survey the area of web caching. We identify major research challenges and their solutions, as well as several commercial products that are being widely used.
