oh, that's a shame, I knew there was some security with IE, but since I only need to know if there is a forward page available and I don't need the url, I was sure there was a way to know. Because what I need to do, is to run a javascript function only if the page is not loaded after a back(because if not a got a layer that stay open in the middle of my page and should not)
I don't suppose there is any other way to know?
My only remaining solution is to use a cookie but only if I have no other choice.
