I have a domain abc123.com and a second domain def456.com. I've setup def456.com/forum. However I want users to goto and only see forum.abc123.com.
The forum is SMF. Could anyone point me in the right direction? Maybe I have to use Apache ReWrite rules? I'm not sure.
To be clear, I never want the user to know they are actually browsing on the def456.com domain.
