I have a Portal that uses Forms Based Authentication. When the user enter a valid user and password, my app generates a tiket informing that the user was logged. With this, I could see restricted pages on my portal. Then, i get a link to a secure page and save it to the clipboard. After this, i click on the logout button, that call the FormsAuthentication.SignOut method. So, the system points me back to my login page. But, if I try to access the address that i copied to the clipboard without re authenticate, the system permits the vizualization. Does anybody knows what could be wrong?
