It’s good for search engines, like Google, to only have one version of your website indexed. To Google, the www.yourdomain.com and yourdomain.com are not the same. You can use this code on Apache servers inside a .htaccess file. It’s worked for me on several different hosting companies.

To redirect to without www version:

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

To redirect to the www version:

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