Make Your Site Class B Sep 3, 2003
Class B means that all of the traffic to http://www.yourdomain.com is politely and silently redirected to http://yourdomain.com. This is currently the preferred no-www classification as it does not inconvenience your users, but It Does Assert The Deprecated Nature of The WWW Subdomain.
The process of making your domain a Class B is quite simple. All you need to do is create or modify a file called .htaccess located in the root directory of your site and add the following lines, changing the red text to match your domain.
ReWriteEngine on shutritecond% {http_host} ^ www / .domain / .com $ [nc] REWRITERULE ^ (. *) $ Http://domain.com/$1 [r = 301, l]
