Using .htaccess to Prevent www Subdomain

Multithreaded JavaScript has been published with O'Reilly!

You can use the following rules in your .htaccess file to force users to visit your website without the www subdomain. Your users will be 301 (Permanently) redirected to the same path, but at your domain without the www.

This is a really simple thing to pull off, however I haven't seen any other websites talk about it, most people want to force users to have the www.

RewriteCond %{HTTP_HOST} ^ [NC]
RewriteRule ^(.*)$$1 [L,R=301]

This should work with any website assuming it is hosted with Apache, and that both the normal domain and the www subdomain both resolve properly.
