Apache2 server consultation

I need some consultation I setting up apache to work with some web apps. Here is what I'm looking to do: 1. Have a virtual host pointing to a simple site 2. Have dynamic virtual host files for each app pointing to a directory where multiple clients of the web app will exist. Essentially this is how I would like it to work. [login to view URL] -> /home/mycompany/site/ [login to view URL] -> /home/mycompany/apps/app1/sites/client1/ [login to view URL] -> /home/mycompany/apps/app1/sites/client2/ [login to view URL] -> /home/mycompany/apps/app1/sites/client3/ For the client sites, I assume it can be done using wildcards in a virtual host file? This way I don't need to append new settings to the vhosts file everytime there's a new client. One last thing is I'd like to have preview urls as well. So I should be able to look at [login to view URL] by going to [login to view URL]~[login to view URL] I have a rackspace cloud server and I'm using Ubuntu karmic server.
