Virtual Dedicated Hosting

I have three domain names and one virtual dedicated hosting account. How can I host all three domains there?
example domain1 should point to /var/www/html/1/ domain2 should point to /var/www/html/2/

Check out apache with virtual host.

Wilcard DNS (similar to hosts file) in Windows without a local dedicated DNS server...?
I have a local test server running Apache2 with virtual hosting setup correctly. I'd like to set up a system so that *.dev is redirected to my testing server at 192.168.0.4 I know I can do this for each individual site using the hosts file found in C:\WINDOWS\system32\drivers\etc\ Unfortunately the Windows hosts file doesn't work with wildcards! I don't have a dedicated local DNS server, but I'd like a system that redirects *.dev to my server without the need to open and edit the Windows hosts file every time. Do you know how this can be achieved? Thanks in advance.

Well, if it were me, I would probably just setup a Proxy server for the office. Since you attempting to make a new TOP LEVEL domain type??? I think it is about the ONLY way you will get this to work. (You can use the same "apache2" machine as the proxy!) Hope that helps.
