Logout back button issue

[Saha]

When I logout and click back button on the browser , it shows me the logged in screen . Although when I click on any link within the logged in state it than redirects me to login.

Ideally It should show me login screen right away when I click back button on browser .

That's what my browser (Firefox 59.0) does. Apparently you have some caching mechanism in place which keeps the previous page. Thirty bees is placed on the server, so it can't do much about how your browser behaves.
