Other reviewers are right, this book doesn't deserve the O'Reilly reputation. This book organizes information loosely, and if you are clueless about Apache, reading this book wouldn't really benefit. Though, if you treat this book as a story book, maybe you can still read it, but don't expect much.If you want to spend your time better on the Apache subject, try the "Professional Apache" by Peter Wainwright by Wrox, which is a really "definitive" guide. (With that book I finished my domain name and virtual hosting within a few hours, marvelous by my standard.)
