Product Description
Just as TCP/IP is a central protocol for the Internet, HTTP is a central protocol for the web. They are both critical for web networking. Web Protocols and Practice is the most authoritative and comprehensive guide to the Web's technical underpinnings. Authored by legendary AT&T Labs researcher Bala Krishnamurthy and renowned Web networking expert Jennifer Rexford, this book offers exceptionally thorough coverage of core Web protocols-including the most detailed discussion of HTTP /1.1 and its relationship to TCP/IP networking ever presented. The authors begin with a broad overview of the evolution of the Web, including its naming infrastructure, HTML document language, and HTTP message exchange protocol. Next, they introduce the inner workings of clients, proxies, and servers, as well as scripts, handlers, search engines, cookies, and authentication. The heart of the book is a detailed discussion of the core Web protocols DNS, TCP/IP, and HTTP. An essential resource for all networking and Internet professionals, and for all developers building Internet applications.
Amazon.com Review
Carefully prepared content gets all the glory, but the job of delivering multimedia information to the people and machines who require it falls to a set of protocols. Web Protocols and Practice explains how resources locate one another on the constantly changing Internet, how they ask for other resources, and how those documents and media are delivered. This comprehensive document does more than any other book around to eliminate vague hand-waving and actually explain how the Internet works. Anyone who's heard explanations along the lines of, "The Domain Name Service resolves the machine name to an IP address" or "The browser makes a POST request" and wanted to scream "But HOW?" will love what Balachander Krishnamurthy and Jennifer Rexford have done in these pages.
The authors approach HyperText Transfer Protocol (HTTP) and the other protocols covered from an engineering perspective, which is to say that they outline the problems the protocols are meant to solve before going into detail about what the protocols do. They also explain the evolution of protocols over time, and call attention to the shortcomings of protocols and their likely evolutionary paths. Nearly all of the explanatory material takes the form of bright, carefully considered text that's supplemented by message listings ("The server could reply with...") and a handful of conceptual diagrams. Later chapters transcend the protocols themselves to focus on questions of reliability, traffic measurement, and efficient caching. --David Wall Topics covered: The protocols that underpin transactions on the Internet and other networks that employ Internet communications standards. Detailed coverage goes to the HyperText Transfer Protocol (HTTP) versions 1.0 and 1.1, the Internet Protocol addressing scheme, and the Transmission Control Protocol specification. Design of Web servers, cache servers, and proxy servers gets much attention, as do site workload and traffic metrics.
