For one of my sites I let users have a subdomain. This was done automaticly and thus I no longer know all the subdomains. Now that I am on a new sever, all subdomains are deleted. Yet alot of sites and search engines link to the subdomains. How can all radom subdomains be redirected to the main domain?
Well, the subdomains no longer exist right? You should be able to create a custom 404 error page that automatically redirects to the main domain via a meta tag refresh in the error page. -Jon
