Creating Subdomain Affiliate Links For My Website! HELP

I currently own a website called: www.mrboredom.com. We want to sign up certain individuals and give them there own custom subdomain to the website to bring us traffic. Therefore, we will be able to track the said subdomain name that we give them individually, through analytics and through adsense. I don't want the subdomain to redirect to the main domain and be changed. Rather I want the subdomain's URL to be permanent in the address bar wherever the user clicks/whatever links the visitor visits when on said subdomained link. The subdomain should merely reflect EVERYTHING the main domain has, content wise, theme wise, design wise. If you don't understand that here is another explanation: "I have a primary domain ([login to view URL]) and I would like to create a subdomain ([login to view URL]). The purpose of creating this subdomain is so I can give the subdomained URL to an affiliate of mine and track the amount of traffic being sent to this subdomain (Analytics) and the amount of money he produces from his subdomain (Adsense). Thus, I need the subdomain to be a LIVE reflection of the primary domain. Sharing the same content/database? across the two.. An example of something I found is: Primary: [login to view URL] SUBDOMAIN: [login to view URL]" If you are able to do this that would be amazing as my efforts, and Im quite proficient with all of this stuff, is not achieving anything. Thankyou!
