As a seasoned system administrator, I can appreciate the need for a comprehensive treatment on the critical subject of server load-balancing and traffic management, yet Mr. Bourke's attempt is a painful and useless read. The book is overly simplistic, and offers no new insight. Mr. Bourke's writing is awkward and confusing at times as well.

I have come to expect a lot more from O'Reilly books. Nonetheless, I will continue to purchase your titles, despite this one bad apple.
