Webserver basics
Apache version 2.2, with several custom tweaks, is included with every copy of os X.
These tweaks can confuse the long time apache, first time os X user.
/Library/Webserver/Documents is the storage area for web documents, the web server document path.
This path is often referred to as htdocs, httpdocs, or something similar in linux/unix variants.
It is not necessary to be connected to the web to access the builtin webserver on the local machine.
Enter the url http://localhost/ into a web browser (Safari) on the the local machine to load a page with more details.
Use the OS X Finder application to browse to /Library/Webserver/Documents/ for an idea of how files in the file system get served by the Apache server.
