Performance is critical to the success of any web site, and yet today's web applications push browsers to their limits with increasing amounts of rich content and heavy use of Ajax. In this book, Steve Souders, web performance evangelist at Google and former Chief Performance Yahoo!, provides valuable techniques to help you optimize your site's performance.

Souders' previous book, the bestselling High Performance Web Sites, shocked the web development world by revealing that 80% of the time it takes for a web page to load is on the client side. In Even Faster Web Sites, Souders and eight expert contributors provide best practices and pragmatic advice for improving your site's performance in three critical categories:

• JavaScript--Get advice for understanding Ajax performance, writing efficient JavaScript, creating responsive applications, loading scripts without blocking other components, and more.
• Network--Learn to share resources across multiple domains, reduce image size without loss of quality, and use chunked encoding to render pages faster.
  
• Browser--Discover alternatives to iframes, how to simplify CSS selectors, and other techniques.

Speed is essential for today's rich media web sites and Web 2.0 applications. With this book, you'll learn how to shave precious seconds off your sites' load times and make them respond even faster.

This book contains six guest chapters contributed by Dion Almaer, Doug Crockford, Ben Galbraith, Tony Gentilcore, Dylan Schiemann, Stoyan Stefanov, Nicole Sullivan, and Nicholas C. Zakas.

This is by far the best ‘know all, end all’ reference, bar none. My hat goes off to Peter Wainwright and Apress for opening up a whole new world to me." — Eric Wolf (a.k.a. "nawlej"), Codewalkers.com This book aims to teach you everything you need to know to build, install, and configure every aspect of Apache, the world's most popular Web server. Two versions of Apache are now available. Apache 1.3 is still widely used and is continuously updated. Apache 2 offers new and powerful features, such as multi-processsing modules and filters, as well as a revised and expanded build system for compiling Apache from source. This book comprehensively covers both server versions, presenting up-to-date information and examples, and highlighting variations bettween the two releases in context. In addition, this book is organized to provide solutions to common problems. It answers the questions that administrators like you typically ask, without requiring that you know the name of a specific Apache module or directive beforehand. This book also demonstrates multiple solutions to a problem, and contrasts the benefits and drawbacks of each approach. After reading Pro Apache, you'll know not only how to get the results you want, but also why a solution works the way it does. Finally, this book examines how to accomplish more advanced configurations, where individual features must cooperate with each other intelligently. Now in its third edition, the expertise found in Pro Apache makes it the definitive guide to harnessing the power of Apache safely and securely.
