[Ilugc] Disabling the refresh and back button in browser

[Raju s]

Hello,

I have done an online examination application in jsp.
I want to disable the back and refresh button.
When googled there are many scripts and none of them are working in all the
browsers.
The advice from the experts is that you should not do the disable.
My problem is when the user clicks refresh or alt+ or back the time gets
reset to the beginning.
Pl. advice.

Thanks
Raju
