Adding Custom Pages as Sub Domains with Content From Some Sections

[p0lar_bear]

In order to have a sudomain system like that, you host needs to to be able to support Wildcard DNS.

Also, to set it up yourself, you need an understanding of Apache's mod_rewrite module, .htaccess files, and regular expressions. It's by no means easy, and I'm having difficulty understanding this myself; there's a whole site about it at http://www.modrewrite.com/.

Your goal is to use mod_rewrite to internally change the uri from http://sports.mydomain.com/ to http://mydomain.com/forums/index.php?tab=sports (or something of the like), and also have it append all other variables (such as forum IDs, post IDs, etc) to the uri as well.

If your host cannot support or set up a wildcard DNS for you, then an alternative is to go about rewriting http://mydomain.com/sports/.
