I'm looking for a specific WP plugin, but don't know if it exists. Basically, I have a post on my WP blog at www.mydomain.com/my-fav-post. What I want to do is that when Referrer A comes to view the post it is the actual post. But when Referrer B comes to visit the post it is a modified white hat version of the post. Is this possible with WP?? Any help is greatly appreciated, thank you.
