Forums / Cotonti / Support / Mod_rewrite subdomain capabilities?

Okay, I did a quick search, so shut your mouths. ;)

I haven't gone through and tried it yet, but I got 20 some subdomains... was wondering if at all possible to set up mod_rewrite to utilize subdomain folders.

For example:
blahblah/forums
forums.blahblah.com

I have previous experience in utilizing mod_rewrite to change extensions to "folders" or basic ".html" files; however, did not know if there was a set back in using subdomains with or without changing the actual extensions.

Would this be just more of a simple little point a subdomain to folders in Cotonti core file skeleton, or...? Then use mod_rewrite to rewrite extensions...

Basically, wondering anyone else's experience in this; as I am unsure that if I do this and since Cotonti only knows the BaseURL type configurations... if doing this would mean my custom links go to subdomains and Cotonti generated links would then go to the folder designated and drop the subdomain.

Just curious.
