I would like to modify my .htaccess file so that if someone tries to access any subdomain.mydomain.com URL, it will actually work and display a given page. The page will be the same for any subdomain they put in, but I don't want it to be a redirect to another URL. Does that make sense? Is that possible? If anyone can help me out with this, I will give very thankful talkupation.

I think you would be better off making an A dns record change

I cant just do it easily with a .htaccess file?

I am not 100% sure, but I don't think, only htaccess will be able to do that. You will need to set up a wild card A record to point to the main domain where you put the modrewrite rules in htaccess to point to the page you want to direct to.

You are definitely correct.
Before you can use .htaccess rules to do what you want, you need a "wildcard" DNS setting up so that anything.hostname.tld will resolve to the one virtual site

Alright cool, thanks... Do you know any simple tutorials for configuring the wildcard DNS setting?

Looks like you're already convinced, and I don't know the answer to your new question, but just for the record, anything you do in htaccess will slow the server - meaning your web site - down. Also, htaccess is a nasty, ugly beast. If you can avoid it, even just for your own sanity, this is advised. Personally, I prefer IIS.

Just an observation, but if you run a hosting company ( I'm assuming you do based on your sig ) shouldn't you be telling us the ins and outs of DNS?

HostGator reseller account = free WHM AutoPilot, which I took advantage of, got a few clients, and now my reseller plan pays for itself

Back to the wildcard DNS... I'm going to look up a tutorial and give it a try. Wish me luck.

Good luck!

There's a million tutorials on every subject, I find most of the time it's harder to figure out what to look for than to find step by step instructions. You'll be fine.

just add

*.hostname.tld   14400   IN    A    nnn.nnn.nnn.nnn

to the zone file for the hostname. (nnn.nnn.nnn.nnn being the IP for the server)
Zone file name will be hostname.tld.db if you are using BIND
