Need multiple domainnames pointed to different folders on the same webserver (while masking the original url)

So I have the following scenario: 2 domain names (let's say [login to view URL] and [login to view URL]) 2 webservers So right now [login to view URL] is pointed to the root folder (public_html) of webserver1. [login to view URL] at the moment points to webserver2. What I want is for [login to view URL] to point to a subfolder on webserver 1 (public_html/domain2folder), so when I go to [login to view URL] it goes to that subfolder on webserver1 and it still shows [login to view URL] in the url bar of the browser. When I go to [login to view URL] for example it should go to public_html/domain2folder/folder1 but it should show [login to view URL] in the url bar. I hope I made everything clear, I'm not really sure how to do this. I'm using Directadmin as control panel. I need someone who can do this for me or guide me through the process of getting this to work.
