Redirect include www and subdomain

Ok here goes.

I want to have my site rewrite the URL to www.mydomain.com if the www is missed of the start but also be able to use subdomains like subdomain.mydomain.com

This apache stuff is all new to me and I managed to get the www to rewrite but this stop me being able to use subdomains.

Any help would be appreciated

Thanks

 

Try this rules:

Change ^waww. to www, as I can't post link and the forum treats it as one

 

why dont u just use wp redirector plugin
