But there is much more to apache than these configuration features I described. For instance, there is the mod_rewrite module which is heavily used by most content management systems to provide a easy to remember permanent link to individual web pages and an in depth introduction to mod_rewrite will take up larger part of a big chapter.
Pete Freitag has written a very good article which lists the steps one need to take to secure running Apache web server on ones machine. What I like most about his article is the simple manner in which he explains the various configuration parameters aided with bits of code. A very informative read indeed.
