I have two Linux / Apache VPS servers running Plesk 9.5.4. VPS 1 is the production server and VPS 2 is the development server. At present I have www.domain1.com on VPS 1 and sub1.domain1.com, sub2.domain1.com, sub3.domain1.com on VPS 2.
I want to test some new functionality which involves having two domains pointing to the same website. My new functionality is all loaded up onto sub1.domain1.com on VPS 2.
Now I need to point www.domain2.com to sub1.domain1.com. Not a redirect, but an alias or similar.
Question: How do I acheive this using the Plesk control panel?
