I want to give each user a url like: http://user1.domain.com , But i dont want to create a subdomain or A name for them. This will be just for visual purpose. But the content of the pages will come from actual application hosted on domain http://www.domain.com. It just simply means that all pages will have domain name replaced with subdomain like http://user1.domain.com , http://user2.domain.com, http://user3.domain.com etc
How do i achieve this? Please help . Its very very urgent.
