Domain question need help

I am dying to find out how the following is achieved: look at [[login to view URL]][1] partner program, an affiliate signup an account, then choose color themes, sitename etc to customize the appearance of his affiliate site, then he registered a new domain [[login to view URL]][2], as requested by [login to view URL], point the name server of [[login to view URL]][2] to a certain server address. Now [[login to view URL]][2] is an affiliate site of [[login to view URL]][1], but looks like an independent site with its own domain name, color, font configuration etc. I am sure all of the affiliates' sites point to the same webpages on [[login to view URL]][1], they are not making multiple copies of those webpages and database. If the affiliate login into his account and adjust some configurations, like from red to yellow, change sitename etc. The changes will reflect on its site [[login to view URL]][2] instantly. I am working on a project now that requires similiar features. It is not domain parking, since domain parking does not recognize affiliates. It is not domain redirection either, since they don't change the url from [[login to view URL]][2] to [[login to view URL]][1] when user is browsing, yet it still can credit the affiliate if he made a referral sales. I am really confused and anyone can give lights on how that was achieved and what is behind it appreciate your help ! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
