Web Caching

Web Caching

by Duane Wessels (Author)

Synopsis

On the World Wide Web, speed and efficiency are vital. Users have little patience for slow Web pages, while network administrators want to make the most of their available bandwidth. A properly designed Web cache reduces network traffic and improves access times to popular Web sites - a boon to network administrators and web users alike. This text provides the technical information needed to design, deploy, and operate an effective Web caching service. It starts with the basics of how Web caching works, from the HTTP headers that govern cachability to cache validation and replacement algorithms. Topics covered in this guide include: designing an effective cache solution; configuring Web browsers to use a cache; setting up a collection of caches that can talk to each other; configuring an interception cache or proxy; monitoring and fine-tuning the performance of a cache; configuring Web servers to co-operate with Web caches; and benchmarking cache products. The book also covers the important political aspects of Web caching, including privacy, intellectual property, and security issues.

Media Reviews
'It provides a good general introduction to caching solution. If all web sites follwed the suggestions on cache-friendliness then the web could be a much faster and more efficient place.' - Andrew Cormack, new@UK, December 2001
Author Bio
Duane Wessels discovered Unix and the Internet as an undergraduate student studying physics at Washington State University. After playing system administrator for a few years, he moved to Boulder, Colorado, to attend graduate school. In late 1994, he joined the Harvest project, where he worked on searching, indexing and caching. From 1996 until 2000, he was co-principal investigator of the NLANR Information Resource Caching project (IRCache), which operated several large caches throughout the U.S. During this time, he and others developed and supported the Squid caching proxy. In 1999, his team organized the first Cache-Off, a performance benchmarking event for caching proxies. Currently, he is co-owner and president of The Measurement Factory, Inc., a company that specializes in evaluating the performance and behavior of HTTP-aware devices. Like many other Colorado residents, he enjoys hiking, bicycling, and snowboarding.
