I currently have a large amount of domains pointing to a single domain. I used cPanel's Park function to do this.
The domains all have unique content -- they are all pointed toward the same PHP script which does something unique for each domain.
I would like to add a subdomain for all of these domains. It's the same subdomain for them all -- m.*
So I want:
m.domain1.com, m.domain2.com, m.domain3.com, etc.
This sub domain should point to the exact same domain/PHP script that www.domain1.com, www.domain2.com, etc., point to. Again, the PHP script will decide what content to display if the user used the m.* subdomain.
Is it possible to do this easily, or do I need to open each domain's control panel (cPanel) and manually add the subdomain?
