Query: excellent book

I bought 'Apache server bible', this book does not cover enough on Apache server. So, I bought another book 'Apache server administrator's handbook', I still was disappointed from what I can learn from the two books. I have had many questions unanswered for many months. Finally, this book resolves all my unanswered questions. This book can replace both the above two books plus more. I am so pleased that I read the right one now. If this book was published earlier, it would save me lots of time and money.
