Thank you so much for a quick answer!
I guess directing the domains to the same server is not really a problem. The issue really is, once this is done, how do i get the server to understand that all those domains MUST use the same webspace.
The idea is to run the exact same scripts on all urls. The application will load the right content depending on the requesting url, but the idea is to run the application from the same space, instead of installing it on every webspace assigned to the url.
I'm pretty sure it runs on Apache.
