The Apache HTTP Server is a robust, commercial-grade open source Web server developed by the Apache Software Foundation ( Red Hat Enterprise Linux includes the Apache HTTP Server 2.2 as well as a number of server modules designed to enhance its functionality.

The default configuration file installed with the Apache HTTP Server works without alteration for most situations. This chapter outlines many of the directives found within its configuration file (/etc/httpd/conf/httpd.conf) to aid those who require a custom configuration or need to convert a configuration file from the older Apache HTTP Server 1.3 format.


If using the graphical HTTP Configuration Tool (system-config-httpd ), do not hand edit the Apache HTTP Server's configuration file as the HTTP Configuration Tool regenerates this file whenever it is used.
