mod_rewrite wildcard subdomain

[BigToach]

I didn't know where this should go. anyways you apache guru's
I am trying to get mod_rewrite to have a wildcard subdomain to direct users to a php script.
something such as
(www\.)?[^.]+\.mysite\.com /somepage.php?subdomain=$1 [L,T=blah-PHP]
i have been testing it locally on my apache but i cannot for the life of me get it to function right.
anyways anyhelp is GREATLY appreciated.

First of all, do you have DNS wildcarding set up on your account? You'll need this before anything will work. You can test for it by typing anything.yourdomain.com into your browser. IF you get your usual homepage, you ahve it. If you get an error, you don't.

Instead of mod_rewrite, consider adding code to your site's hompage that checks requested HTTP_HOST and does the forward from there.

<?
    if($_SERVER['HTTP_HOST'] != 'www.yourdomain.com' ||
      $_SERVER['HTTP_HOST'] != 'yourdomain.com') {
        header("Location: /somepage.php?subdomain=<whatever>");
    }
?>
Page content
