Im trying to figure out how to make people go throw a redirect so they can no longer go back anymore.

any help apperciated

I know what you're talking about and i don't know for sure, but at a guess i'd say have them go to an url which is then redirected to another url and then when they press the back button they get back to the first url which again will redirect them to the second.

I'm not sure if that works but might be worth a shot?
