i hear that even if the subdomain are not allowed to make on some domain ..like sms.somedomain.com now when what i think is that when some page is not found on somedoamin it searches for 404 error page...which can b customized.. what if that 404 error page is customized in such a way that.. it picks up/records the subdomain that was requested and then redirects the visitor according to subdomain searched for..
like.. www.loop.com is the main domain
sms.loop.com is the search domain searched for which actaully doesnt exist..
404 page records /captures the request and then redirects the user to URl like www.loop.com/fix/sms/index.php
can it b done?
