using mod_rewrite to redirect from subdomain to maindomain

Question

My problem is that i have a functioning subdomain (sub.mydomain.com). sub is loaded in mydomain.com/sub.

What i would like to do is to redirect all requests to sub.mydom

It's difficult to provide a definitive answer without knowing more about your server configuration.

The following might work and is at the very least a decent starting point:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^sub\.mydomain\.com 
RewriteRule (.*) /$1 [L]

Ideally that would go in your httpd.conf, but might work from a .htaccess file (again, more information about how your subdomains are setup would be helpful).
