I am trying to stop the user from being able to go back to the previous page. In doing so I decided to write a cookie to on the next page and if that cookie exists I do not want it to run the page but rather tell the user they can not reaccess the page. My question is after the cookie is set is not read if I use the back button however if I go to the page manually,the one I dont want the users to be able to access when they press the back button, it will tell me I can not access the page which is what I want. Why does it not read the cookie when I press the back button.
