注销和浏览器后退按钮

Question

我正在尝试退出我的会话。注销成功但是在按下后退按钮后，我被带回“秘密”页面，我可以访问所有链接等...

这是我的“秘密”页面：

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"); 

Answer 1

 <script type="text/javascript">
 function doLogout() { 
     var backlen = history.length;
     history.go(-backlen);
      window.location.replace("index.html");
 }
 </script>
 <a data-role="none" href="#" onclick="doLogout"></a>

Answer 2

把代码放到这样......

if (check session is alive){

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