[Javascript] Navigation Control - No back button?

[Rees, Mark (TWIi London)]

Hello

Anyone who really really wants to go back can do so by for example using
backspace along with the back button on the browser - you can circumvent the
suggestion below by doing so.

So, by all means try to prevent the user from going back, but your best bet
is to do a "if not exists" type statement before the DB insert to avoid
duplicating data

Cheers

Mark

try putting an inline javascript command history.forward() this will
immediately take the user forward again preventing the back button from
wactually having an effect. This combined with expiring the previous page
should create the scenario you are looking for.

All the best
