Hello,
I have created a test site with asprunner 5.1. I want to setup a store where people can buy items. Now I wonder how I can setup IPN with the ordered item as a querystring. The idea is that if someone orders a product, after paying with paypal he will be redirected to http://www.mysite.com/paymentsucces?itemID=5
This way I can have the asp page write to a mysql table that holds statistics on downloaded items. As far as i have seen you can only give one IPN as a general setting and not for every single item. Is this correct?
Second, one quick question:
How would I set it up so that this same asp page can hold statistics per user, let's say write a record that the item is already downloaded, so the user may not download it again (prevent people from spreading my download link so other people start downloading directly). I know this can be done when i let users login and then order. This way i will have their username to put in the querystring, but if i want an open store that everyone can visit, how would i track an unique user (request.servervariables("Logon_user") may not be an option since it varies if a user buys at work, but uses it at home)
Any tips would be greatly appreciated!
Hans
