Apache is far and away the most widely used web server platform in the world. It runs about half of the world's existing web sites and is still increasing market share. The Apache Pocket Reference, covering Apache 1.3.12, is a companion to Writing Apache Modules with Perl and C and Apache: The Definitive Guide, 2nd Edition. A handy referency guide to this popular web server, it provides a complete overview of the command-line options, configuration directives, and modules, and covers Apacher support utilities.
