Hi I have something to fix I have cpanel on my server and i cant make it in it becouse it is in my hosting company. I want any not existing subdomain to go to my main subdomain like blabla.cos.pl to cos.pl exept real made subdomains takes me to sites. it is possible? I have script like that: $host = getenv('HTTP_HOST'); switch ($host): case 'www.cos.pl': header("Location: http://cos.pl"); break; default: header("Location: error404.php"); case 'cos.pl': endswitch; It is possible to do that?
