Help with mod_rewrite ****500 POINTS URGENT****

in the apache configuration file for 2.0 what can I put using mod_rewrite to just add a www. when there is no subdomain because I want other sub domains like forums.mydomain.com to work without redirection but if it is just mydomain.com I want it to change the url to www.mydomain.com but keep anything after the domain name for example if someone goes to http://mydomain.com/?action=login I want it to redirect to http://www.mydomain.com/?action=login also I want it to just basically change the url so in the browser history they don't see http://mydomain.com then http://www.mydomain.com only the one with www.

to force an external redirection, you can use

RewriteEngine on
RewriteCond %{HTTP_HOST} ^mydomain\.com
RewriteRule ^/(.*) http://www.mydomain,.com/$1 [R=301,L]

inside your <virtualhost *>-container for your domain.
