Clickbank dynamic programming language

I'm selling products on Clickbank and I need someone who has DONE the following: "The CBF Session Identification Parameter" The cbf session identification parameter allows me to offer PitchPlus Upsells to customers with disabled browser cookies (approximately 10% of customers). I'm not required to use the cbf session identification parameter; however, if it is not used, customers with disabled cookies will be redirected to the standard order confirmation page, rather than my first PitchPlus Upsell Pitch Page. When the customer makes a purchase, ClickBank will pass the cbf parameter to my first PitchPlus Upsell Pitch Page. I must then capture the parameter and pass it back to ClickBank in the payment link. This may be accomplished using a dynamic programming language such as Perl, PHP, JSP, ASP .Net or others. I'm not experienced with dynamic programming. An example of how to retrieve the parameter using PHP is: $_REQUEST['cbf'] Example payment links: [login to view URL]<parameter passed> [login to view URL]<parameter passed>
