User Web Siteson Ares
The webserver on ares is configured to look for a directory in each user's home directory called public_html.
If this directory exists and is world-readable, then anything that is in that directory will become accessible
through the webserver.
Say the user jstevens makes a directory called /home/jstevens/public_html, and puts some files in it.
Anybody can now see those files by visiting the website http://www-ra.phys.utas.edu.au/~jstevens.
The webserver is configured to load the file index.html whenever a directory is specified without a specific
web page; if a user wants visitors to see a webpage when they load their site, then they should make at least
this file. If this file does not exist, then the webserver will show a list of files in the directory.
