I read this over the summer. You would be better off saving yourself the money and going to apache.org. This book lacks important details for anyone that is new to apache. She expects to much out of the reader. The way she suggests to implement apache is confusing and useless. I believe this book is outdated as well. I just purchased Web Application Design and Implementation: Apache 2, PHP5, MySQL, JavaScript, and Linux/UNIX (Quantitative Software Engineering Series)by Steven Gabarro. Hopefully it will be better than this train wreck definitive guide.
