当我点击后退按钮时，我可以看到我上次受保护的页面

Question

In my web site I destroy session but after logout if users press back on browser they can see last page.

How can I solve this ? I tried javascript but didn't work. I tried unset or destroy session but that doesn't work too. What I can do ?

I use these codes at header.

Header('Cache-Control: no-cache');
Header('Pragma: no-cache');

How can I solve this. Thanks for your help.

You can't. The page was sent to the client, it's up to the client to decide what to do with it.

What's the difference between this behaviour and a user with a photographic memory?

The real question is: why would you want to do this?
