I use a tracking url of the form www.website.com?trackingurl to track from which site do my traffic come from. However, to track sales, i would need the tracking url to transfert to every page the customer visits. ex customer gets on the site under www.website.com?trackingurl then visits www.website.com/join.php i would like it to come up as www.website.com/join.php?trackingurl how can i do this?
you can store the tracking information in session variable . what is the programming language you are using ?
