Hi,

In navigateLogin function, write ajax call to some server side function to clear your session and navigate to login page.

or

In navigateLogin fuction, navigate to login page and kill the session on the login page load.

<title>

Nope. Not remotely possible. Fix your code so that it doesn't cache logged in pages. You can't control the back button, your page will refresh same as before and any attempt to make the back button log out will be fraught with danger, and dumb design.

but in some bank websites they are having this feature.How they doin it

Christian Graus 13-Dec-12 4:10am

No, I don't think they do. The fact is, if you write javascript to try to spot when the back button is pressed, it's trivial for a hacker to attack that. So, no-one should ever do it, it makes zero sense. The only logical way to do it, is if the whole site keeps track of what pages are requested in a session, and if it notices an order of requests that seems odd, it logs you out. A big job for a stupid result, only sensible for someone like a bank, trying to kick you out if you do ANYTHING that might mean you're trying to attack them.

if we does that means it will be a security issue for us.

I don't understand. Why do you have a security issue ?
