Here's my idea but getting stuck on how it's done.

looking to hand out links to a capture page where affiliates place their companies id on the end

website.com/?ref=1
website.com/?ref=2

the capture page will redirect customer to a product page. The links on that page however will be coded to whatever capturepage sent the customer

salespage.com/?ref=1
salespage.com/?ref=1

simply the links on the page will be coded to the referrer

Thanks
