If you are using an apache server, you can do it with .htaccess. Here is a tutorial on how to do it with .htaccess:

If you are on apache server and your hosting provider allow .htaccess then place this on htacces.

RewriteCond %{HTTP_HOST}   !^fully\.qualified\.domain\.name [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^/(.*)         http://fully.qualified.domain.name/$1 [L,R]

Code (markup):

fully qualified domain name = www.domainname.com

 

Thank you guys

 

A thanks from me too, I always wondered about how to do that and now i know, thanks again!

 

Another good one is at http://www.yes-www.org/redirection/

 

Is this the same as a 301 redirect?
If not wouldn't be better to do the 301?
