Rewrite question - domain.com -> www.domain.com

I'd like to push any traffic coming to simply domain.com to www.domain.com. I _think_ this is the correct syntax, but I'm not sure. Any insight/corrections would be appreciated.

Code:

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

Hello,

your code is correct.

Thanks as always Oleg!

I put the code above in a .htaccess file in my root folder.

Club3G still works though. Any ideas?

Code:

Options +FollowSymLinks 
RewriteEngine on 
RewriteCond %{HTTP_HOST} ^domain.com [NC] 
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]

This is the whole code that needs to be used.
