I’m playing around with different htaccess rules for a while now and can’t figure out, how this should work. I think I don’t get the clue how this will work with htaccess.
The condition has to rewrite just the URL from http://www.domain.com/forums to forum.domain.com. So all bbPress stuff isn’t redirected within the database etc. I think this is what I need. Am I right?
You mean via DNS redirecting?
