Mask URL Solution

We need a simple solution to change the appearence of an url. Example lets say we have this url [login to view URL]://[login to view URL] We would like it to look something like this example: [login to view URL] In the example file above [login to view URL] should be a redirect to the orginal url ([login to view URL]) [login to view URL] is a dynamic file that only should exist in that moment. when the [login to view URL] is loaded there should be a cooke & referral check. The referral check makes sure that the visitor came from the [login to view URL] domain and the cookie check is looking for if there is an existing cookie set from the domain www.domain.com. If YES then let the visitor see the destination url. If NOT then send them to another set page we have chosen. The solution way must also update a template page so the destination link in that template page also is the same as in the url. We are not programmers so if you understand what we want and have a better solution we are open for suggestions. In short, we want to scramble/hide a part of an url and implant referral and cookie check. It's also VERY important that the solution is server resource friendly since it will be subjected to hundred of thousands daily visitors.
