export scripts

If someone can toss me an idea, I'd greatly appreciate it .

I need a script that will run from my server upon credit card approval and is accessible via a web browser. Here is the rundown of what I'm trying to do:

The customer submits the credit card information, and the creditcard validation server sends off the information to the issuing bank for verification.
Upon receiving an approval code for the transaction, creditcard validation company sends out their own TEXT based browser in the background, meaning that the customer never leaves the creditcard validation company's page. This browser has the ability to pass what ever information I require and pass it to the page that I request. This includes all of my own custom variables; the goal is to have a mysql query activate and display the appropriate page (which resides as a blob in my database) requested by the variables. The 'Browser' waits for a completed signal, and the regular transaction process completes.

Ideas, comments and theories are welcome... I'd like to keep what little hair I have left.
