Force loading your site with WWW or without WWW

If you want your vistors to see either www or not in your address bar regardless of what url they typed in to reach your site, you can do so by using the following codes in your .htaccess file in your websites root directory.

Force WWW:

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

Force Non-WWW:

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