I spent a couple hours trying to setup some vhosts in Apache2 for developing some web applications.  The annoying thing is that my IDE (Eclipse/Aptana) uses a directory in my Home folder to store my projects.  Therefore I needed to create a vhost to point to those project folders.

What is more easy is to use the default Apache2 setup and put symbolic links in /var/www/ for each of your projects.  Soooo much easier!
