Track refer code to an order in my site

[machocr]

Hi this is the scenario: The users of my site can get a link with a refer code (query string) to promote their products on their blogs or sites. I want to track those codes so if a order is created I can give points to refer users as a kind of omission. The problem is before visitor creates an order he/she needs to log in or even register to the site. So I'm looking for a way to trap that code once the visitor enter to my site and don't loose it when he\she log in with a new session . :confused: I was thinking to store that code in the session or profile but it will change once the visitor logs in. In brief I need to capture a refer query string value once the visitor came to mi site, store it and if he/she log in and create an order I can know whow refer him/her. I'm using asp.net 3.5. I'm going to try some things but I would like to know if you can suggest me something. Thanks ;)

1 - You get a request with the code in URL as query string. 2 - Keep that in a session. 3 - When user logs in, check this session's value. If session has value, take the code and proceed.

I didn't understood this. How come a value stored in session changes when user logs in? :)
