I'm a bit confused on how to setup sub domains within ISPConfig. I see the co-domain feature, however this doesn't work like a true subdomain. If I make a co-domain forum.domain.com and point it to domain.com/forum, it just rewrites the url. So if I visit forum.domain.com it redirects to domain.com/forum. I do not want it to do this. I want the address bar to say forum.domain.com not domain.com/forum. I can easily do this by modifying my httpd.conf file but I would prefer to do this through ISPConfig. Is this possible?
