关键错误会话不会在Kohana 3.x中破坏

Question

I am developing one of web application in kohanaphp latest version. While user logged into application, I set the session as usually. Everything fine. Once i logout the application which clear the session.

Then I am checking in all functions whether user id exist, if it exist, it will work, otherwise it will goes to login page.

But my problem is that, I logged out the profile, while user click on the browser back button, it goes to profiles pages. It should not happened. It should goes to login page. But while user refresh the page it redirect to user login page.

Same things working in older version. But not in latest version.

Critical Bug is Session is not destroying in Kohana 3.x

Can you please any one provide the solution.

Need to add this headers,

 header('Cache-Control: no-cache, no-store, must-revalidate'); // HTTP 1.1.
 header('Pragma: no-cache'); // HTTP 1.0.
 header('Expires: 0'); // Proxies.
