Web Proxy Servers (Web Infrastructure) Paperback – December 30, 1997
From the Inside Flap
Thanks, Ari. You're a fountain of information as usual.
During the four years that I have worked on the fast-evolving World Wide Web technology—specifically proxy servers—I have felt uneasy about the fact that no one has really had time to produce good documentation that would provide true insight and understanding of this great technology. We engineers who understand how things work are often just too busy to explain them to others. After all, an Internet year is just 52 days long, and the average release cycle tends to be less than nine (Earth) months. So many new features, so little time.
I've always taken great pride in promptly answering all the E-mail that I get. But there have been times when I have been completely overwhelmed by the number of messages and the span of questions that I have received. And I've realized that I have explained the same things over and over again in E-mail. If only there were a book that covered all these issues, people could just read it and receive the same answer I would give them anyway—and maybe learn a bit more and gain depth in their understanding about how things work, and why they work like that.
So one day I got an E-mail from Mary Franz at Prentice Hall asking if I'd be interesting in writing a book on Web proxy servers. Well, not being able to say "no" to more work, I said yes, sure, might as well. I have always found working on the Web to be rewarding. It's great to receive messages from the Internet, thanking and praising my efforts.
From the Back Cover
Make the most of your proxy servers!
Proxy servers are critical to the success of virtually every large Web and intranet site. But managing and optimizing them has always been a black art—until now. In Web Proxy Servers, the co-developer of the first proxy server, the CERN Proxy, explains the technology in depth—and shows how to optimize any proxy server in any environment.
Understand the basic architecture of proxy servers, and compare firewall proxy servers, departmental, personal and specialized proxies. Discover how proxy servers handle every major Internet protocol, including HTTP, FTP, Gopher, News, SSL, WAIS, Telnet and LDAP. Learn how to implement filtering by URLs or PICS content ratings. Review proxy server caching in unprecedented depth, including:
- Guaranteeing the freshness of cached documents
- Measuring and optimizing cache “hit ratios”
- On-demand and on-command caching
- Web-based advertising
Discover the best proxy security solutions, including encryption and authentication. Compare proxy server configuration for Web sites, intranets, extranets, and “DNS-deprived” environments. Get troubleshooting tips and sample auto-configuration scripts. Learn all you need to know to maximize performance, including:
- Estimating loads, establishing proxy hierarchies, choosing hardware and software
- Balancing loads with Round-Robin DNS, hash-function based proxy selection, CARP, ICP, and other methods
- Using reverse proxying effectively
Web Proxy Servers is a must-have resource for all Web and intranet administrators who care about performance and security.

The book is somewhat dated, but no worries, it covers HTTP 1.1 and below.
Today, Proxy serveres are a lot like DNS was a couple years ago, not getting a lot of press, not very sexy, but very important to the effective function of many networks. And like DNS was a couple years ago, you can read the RFC's and the manual, but you really want one book that will make you look like a genius. For Proxy servers, this is the book for you.
Ari has done a fanstic job of covering all aspects or Proxy Servers. He provides clear descriptions of all the basics, but also touches on all the advanced "what if" topics where answers are hard to find.
(NOTE: I provide Proxy Server support for Netscape Communications, but the opinions expessed here are soley my own.)
