You be better off reading the man file on apache. The author uses inserts from the configuration file of Apache and does not build on it as if the inserts are sufficient explanation for configuring the program. I am insulted. If you still want to buy this book I have mine for sale in the used section for the fraction of the original cost. This book is a waist of time and money.
