Apache & lighttpd

Apache

You have your own instance of Apache which runs off $HOME/web/apache2.conf. There are lots of comments in that file about what you should and shouldn't change -- please follow them.

You controll apache with sudo /usr/sbin/invoke-rc.d httpd <action> $USER, where <action> is one of:

start
Start your Apache instance
stop
Stop your Apache instance
restart
"Hard" restart (kill and restart the entire process)
reload
"Soft" reload (SIGHUP) -- should be all you need 99% of the time.
check
Check your Apache config file for errors.
test
Test your running Apache process (also reports its uptime).

Lighttpd

Lighttpd runs your media server. You can have as many of those as you like; just ask. There should be a symlink to your media server directories in $HOME/web, but they actually live in /home/media/.
