Here are two sources for PayPal IPN:
DNN has a loop in the beginning of the Page_Load method that captures txn_type and txn_id, which I don't see in the Kona code.
DNN also captures payer email and other information into local variables.
I am trying to make sure that I incorporate some of the security checks that I see in DNN into my MVC IPN.
How do I do what DNN is doing with MVC 2 with Kona as the base?
Is the Kona.Web IPN safe for production, does it need some more tweaking?
