Apache

In the Web server configuration file, or the .htaccess file, append the following commands:

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

or

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

Both options are acceptable.

A reverse redirect (from mydomain.com to www.mydomain.com) is carried out using commands:

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

or

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

Both options are acceptable.
