A long time ago there was a WordPress plugin that let you configure it like so: You make a page and put whatever you want on it - so lets say I have a weight loss blog and I make a page about XYZ Weight Loss Product. The page would be www.myweightlosssite.com/xyz-weight-loss If you visit that URL directly, you see the regular content (a review of the product, etc.). However, the plugin would let you set a random string, so the URL could look like: www.myweightlosssite.com/xyz-weight-loss?ref=232nakrew7kn (or whatever) And anyone who visited through that link, it would set the page as the referrer, and then redirect them to whatever URL you want. In this way if anyone were to review your traffic and visit the URL, they'd see your nice review page, but any visitors hitting your ref URL would be taken straight to the affiliate page. Does anyone know of any current WordPress plugins that can do this? I could write one myself, but I'd rather just use an already-existing plugin if possible.
