| Overview
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. Web Caching hands you all the technical
information you need 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 book
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 cooperate with web
caches Benchmarking cache products
The book also covers the important political aspects of web
caching, including privacy, intellectual property, and security
issues. Internet service providers, large corporations, or
educational institutions--in short, any network that provides
connectivity to a wide variety of users--can reap enormous benefit
from running a well-tuned web caching service. Web Caching
shows you how to do it right.
Editorial ReviewsProduct DescriptionA properly designed web cache reduces network traffic and improves access times to popular web sites--a boon to network administrators and web users alike. Web Caching hands you all the technical information you need to design, deploy, and operate a web caching service. It spells out in practical detail how to design an effective cache solution, configure both web servers and web browsers to use a cache, set up a collection of caches that can talk to each other, and monitor and fine-tune the performance of a cache. The book also covers the important political aspects of web caching, including privacy and security issues. Internet service providers, large corporations, and educational institutions--in short, any network that provides connectivity to a wide variety of users--can reap enormous benefit from running a well-tuned web caching service. Web Caching shows how to do it right. | Amazon.com ReviewWeb Caching explores the intricacies of implementing caching in Web server environments to reduce network traffic and improve performance. Like so many areas of Internet technology, the topic of Web caching comprises a number of architectural and practical issues that could take a career to learn the hard way. Fortunately, author Duane Wessels has organized all the nuts-and-bolts technical information in this short book. This guide to turbo-charging the Web is primarily geared toward system administrators; however, Web developers can also learn much about the proper--and improper--use of caching their pages. The book begins with excellent chapters on the big picture of how Web caching works, including the various types of caches, hit measurements, validation, and cache refreshing. Before turning to this guide's core focus--designing and implementing caching--the author spends a chapter to explore the political issues surrounding the technology, such as privacy, content distribution, and copyrights. Both client and server configurations are considered, and the benefits of Netscape and Microsoft implementations are explored. The journey through the efficient travels of Web requests is fascinating as you learn about proxies, intercache protocols, cache hierarchies, and benchmarking methodologies for measuring the efficiency of your solutions. Dishing up requests elegantly is not a trivial task on today's Web, but this no-nonsense book is a great help toward that goal. --Stephen W. Plain Topics covered: - Web transport protocols
- HTTP and proxy requests
- Cache replacement and refreshing
- Political concerns
- Client configuration
- Interception proxying
- Server configuration
- Cache hierarchies
- Intercache protocols
- Cache clustering
- Monitoring/benchmarking
- Cache trace analysis

Reader Reviews From Amazon (Ranked by 'Helpfulness') Average Customer Rating: based on 9 reviews. A little dissapointed, 2005-08-12 Reviewer rating: If you have a previos experience in the field this book doesn't give you examples nor ways to discover how much bandwitdh you're really saving. So don't expect much from this book. If you want to have a general line-up of WEB CACHING, this is your book. It explains why caching is important but no more.
I'd rather recommend SQUID:The definitive guide from the same author. That book will answer your questions. | Very approachable, 2005-07-12 Reviewer rating: Really enjoyed reading this one as it starts from the basics and then neatly provides a tight overviews of the major areas without miring the reader in logs. Nicely done! | It's just a plain theoretical book about Web Cache, 2005-01-28 Reviewer rating: If your planning to buy this book and hoping will help you setup good Web Caching infrastructure like Squid, forget it!!! this will not help you..
Unless your teacher and teaching theories about Web Caching and this will be a good materials.. | Great in theory but lacking practical examples, 2003-02-17 Reviewer rating: I bought this one because I knew I was using more server resources than I needed and I wanted to know what sort of things I could do to reduce unnecessary strain on the server. After reading Web Caching, I soon learned that there was more to the topic than meets the eye. The chapter on politics of caching makes for interesting reading no matter who you are on the web; covering topics such as copyright, privacy and trust, offensive content and maintaining content integrity. I also learned more about just how important caching is to the web, which convinced me that I really should make my web pages as cache friendly as possible. Not only does the creation of cache friendly pages speed up the delivery of content, but it can also reduce the cost of hosting individual web sites! As you can imagine, there is a lot of discussion in the book about the communications between server and browser that many of us do not see. Most of this discussion focuses on the use of HTTP headers, but there is little discussion about using various scripting technologies to over-ride the default headers that are used by the server. Even an Appendix chapter to compliment the Perl example given would have been nice, as not everyone has access to their server's settings or knows how to use their language of choice to generate server headers. All in all Web Caching is an interesting book to read as it certainly makes you think about the issues surrounding the subject. I can't help feeling however that this book was written mainly for the server administrators, as practical examples for those that have no direct control of the server are somewhat lacking... | A must read, 2001-12-30 Reviewer rating: If you are looking for a configuration for the Squid Proxy Server, this is not the book for you; if you are looking for an insightful examination of the concepts, configurations and conflicts that surround the topic of content caching, read on. Mr. Wessels book examines a number of different aspects of Web Caching, from the scope and syntax of basic cache control messages available in .../1.0 and ..../1.1 to the legal issues that surround the storage of Web objects in cache servers. This book is a must read, for Web designers and system administrators. |
