Hello,

I am developing an ASP.NET shopping cart that uses PayPal for payment processing. I would like to find a way to post the shopping cart variables to PayPal without displaying them in the URL.

I have been searching for hours without being able to find a solution to this question. It works fine when I pass the variables through the URL, but I don't want my customers to be able to see the variables that I'm passing to PayPal. I'd appreciate any help or advice.
