I wish to redirect all traffic from world wide web.mydomain.com to mydomain.com, even if there's a particular path (like world wide web.mydomain.com/article)
Can One do that through my domain registrar or does it need to be achieved around the server?
It can be done with simple url spinning :
<IfModule mod_rewrite.c> RewriteCond % !=on RewriteCond % ^www.(.+)$ [NC] RewriteRule ^(.*)$ http://%1/$1 [R=301,L] </IfModule>
