In Web Caching and Replication, two AT&T Labs experts bring together real-world implementations, the latest IETF and W3C technical standards, and the field's most advanced research, offering systematic guidance for maximizing Web scalability and performance. The authors first introduce key concepts of Web caching and replication.They introduce HTTP's support for caching and replication, and broadly characterize Web behavior, offering practical rules of thumb for optimizing performance. Next, they focus on caching, helping implementers realistically assess proxy caching, deploy proxies in corporate and ISP networks; and utilize cooperative proxy caching. They offer in-depth insights into cache consistency, and caching the "uncacheable" -- including "cookied" and dynamic content. Part III introduces today's best techniques for web replication, offering in-depth coverage of content delivery networks, server selection, content placement, and more. For all networking professionals, IT professionals, and engineers involved with building or optimizing Internet services or equipment; for content delivery specialists and service providers; and for owners of large sites concerned about scalability and performance.

Book Description
Editorial Reviews
From the Back Cover
"Rabinovich and Spatscheck report a wealth of detailed information about how to implement Web caching and replication mechanisms, but more importantly, they teach me how to think about the general problem of content distribution. I'm pleased that there is finally a comprehensive book on this important subject."
--Larry Peterson, Professor of Computer Science, Princeton University
"This book is a remarkable piece of work, well-organized and clearly articulated. The authors have masterfully presented advanced topics in Internet Web infrastructure and content delivery networks in a way that is suitable for both novices and experts."
--Steve McCanne, Chief Technology Officer, Inktomi
As the Internet grows, evolving from a research tool into a staple of daily life, it is essential that the Web's scalability and performance keep up with increased demand and expectations. Every day, more and more users turn to the Internet to use resource-hungry applications like video and audio on-demand and distributed games. At the same time, more and more computer applications are built to rely on the Web, but with much higher sensitivity to delays of even a few milliseconds. The key to satisfying these growing demands and expectations lies in the practices of caching and replication and in the increased scalability solutions they represent.
Web Caching and Replication provides essential material based on the extensive real-world experience of two experts from AT&T Labs. This comprehensive examination of caching, replication, and load-balancing practices for the Web brings together information from and for the commercial world, including real-life products; technical standards communities, such as IETF and W3C; and academic research.
By focusing on the underlying, fundamental ideas that are behind the varied technologies currently used in caching and replication, this book will remain a relevant, much-needed resource as the multi-billion dollar industries that rely on the Web continue to grow and evolve.
The book approaches its two central topics in two distinct parts. The part on caching includes coverage of:
- Proxy caching, including latency reduction and TCP connection caching
- Transparent and nontransparent proxy deployment
- Cooperative caching
- Cache consistency
- Replacement policies
- Prefetching
- "Caching the uncacheable"
The part on replication includes coverage of:
- Basic mechanisms for request distribution, including content-blind and content-aware request distribution
- CDNs, including DNS request distribution, streaming content delivery, and secure content access
- Server selection
Examples and illustrations are included throughout the book. Extensive cross-referencing also enables readers to identify the corresponding parts of each section. Web Caching and Replication concludes with a thorough look into the future. It not only considers how new services can be implemented on caching and replication platforms, but also outlines emerging technologies that will allow for cooperation between different caching and replication enterprises in order to improve the overall performance of the Web.

About the Author
Michael Rabinovich is "one of the few research-ers who are qualified to write this book" (Pei Cao, Cisco Systems). As a leading researcher at AT&T Labs, he has closely watched current trends and state-of-the-art standards and commercial products while both battling "real-life" technical problems and participating in new research in Web caching and replication. In addition to numerous publications in the areas of distributed systems, Web performance, and transaction management, he is a co-author of the CRISP distributed proxy cache.
Oliver Spatscheck is a senior technical staff member at AT&T Labs–Research, where he has been actively involved in building AT&T's content distribution network. His research publications span the areas of security, operating systems, and CDNs. He has also been active in the IETF, working most recently on Content Distribution Internetworking. He holds a Ph.D. in computer science from the University of Arizona.

4.0 out of 5 stars
Good book for researchers,
By CS Doctor "csdoctor" (New York City) - See all my reviews
This review is from: Web Caching and Replication (Paperback)
It is a good book for researchers in Web caching and replication, although we need additional 200 pages in addressing this research area. Overall, very good book if you want to do research in this area.
