Good starting point for web site administrators
This book has an answer to most questions you could have regarding web site maintenance, although it is heavily biased towards configuring UNIX servers. Windows NT, for example, doesn't get much of a mention. Also, many of the examples are written in Perl which was a shame as I was more interested in CGI written with shell scripts.Some topics do not go into enough detail. For example, the section on how to install two servers on a single machine, each responding to different domain names, tells you "what" to do but not "how" to do it.
Where the book does excel, however, is in describing the concepts of how the internet works.
