An unwelcome reminder that not everything that comes from O'Reilly is top notch. This book seems to have been written half heartedly. The explanations of many of the directives in the configuration file seem to be repetitions of online manual contents with the authors not taking the time to provide really useful insights or clarify difficult concepts. The attitude of the book seems to be: "This is what we did to get Apache running on BSD and Windows. If it helps you, great, if not, tough !" I also have a doubt about the technical credibility of the authors. Their advice seems glib and dubious at times. I have run Apache on Windows before without consulting documentation and I expected to learn something useful from this book. Not in the 1st three chapters. Not a great tutorial. Not a very good reference manual. One of the few books I would lend to someone and probably not worry about it being returned.
