Want an easy way to make sure your visitors always see http://yourdomain.com instead of http://www.yourdomain.com? Here’s how to automatically remove the www from your domain (or vice versa).

First, edit (or create) your .htaccess file, using mod_rewrite to either remove the www from, or add it to your domain.

To remove the www from your domain:

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

To add the www to your domain:

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

Next, simply upload your .htaccess file to the root directory of your web server and you should be all set. Be sure to give it a quick test and make sure everything works properly.
