This directory uses Apache Web Server's MOD_REWRITE. Usually, the URL in the address bar follows the structure of the directory where the site is hosted. For example, if the URL is http://www.andyhill.us/inspire/, the directory path is /inspire/. However, within this directory, if the URL is /inspire/songs/, for example, the processing still occurs at /inspire/. I then use the rest of the URL (songs/ in this case) to determine what content to display. The actual content of the songs are contained in text files in the content/ sub-directory. for example, you can look at http://www.andyhill.us/inspire/content/songs/holdonhope.txt, which is rendered here: http://www.andyhill.us/inspire/songs/holdonhope,
