Intro

I am working on an e-commerce website. And we want to add a feature where a user can refer others via a custom link e.g.:

http://mysite.com/a1t2312 or http://mysite.com/?ref=a1t2312 (a1t231 being the referral code).

A user following such a link, will navigate a few pages on the site. And if he reached the 'buy' page and purchases something - the original referrer will get a discount.

The question is:

What is the best method to track the referral code ? Put it in the user's cookies ? Stick it somehow into the session ? Other method ?

Thanks
