Abstract

We describe the design and performance of a caching relay for the World Wide Web. We model the distribution of requests for pages from the web and see how this distribution affects the performance of a cache. We use the data gathered from the relay to make some general characterizations about the web. (A version of this paper is available at http://www.research.digital.com/- SRC/personal/Steve Glassman/- CachingTheWeb.html or .../CachingTheWeb.ps) 1 Overview In January 1994, we set up a caching World Wide Web [10] relay for Digital Equipment Corporation 's facilities in Palo Alto, California.

We added caching to the relay because we wanted to improve the relay's performance and reduce its external network traffic. Clients use the relay for accessing the Web outside of Digital; requests for internal Digital pages...
