注销和浏览器后退按钮

Question

I am trying to log out from my session. The logout is successful but upon hitting the back button, I am taken back to the 'secret' page and I can access all the links etc ...

This is in of my 'secret' page:

if(isset($_COOKIE['ID_my_site'])) 

{ ........... }

else { header("Location: login.php"); } 

And my logout page is as follows:

unset($_COOKIE['ID_my_site']);
session_destroy();

$past = time() - 01; 

setcookie(ID_my_site, gone, $past); 
setcookie(Key_my_site, gone, $past); 

header("Location: login.php");

if (check session is alive){

    header("Location: login.php");
}
