Its really frustrating not being to go back using the back button, it hampers the general flow by which I use most of the websites. Its already 2015 here, why does bank websites not allow back buttons?<p>Bank I used was: ICICI bank.
Banks are extremely slow movers, probably for somewhat valid reasons since every little change must be examined and tested in the extreme for defects, vulnerabilities and regulatory compliance.<p>Adding that it actually takes a fair amount of work to make browser back/forward buttons work in a web application, it is really no wonder that the situation is what it is.
The back button exists, banks can not refuse to allow its use. All they can do is warn against its use.<p>Have a unique hidden input for every form. If a user goes back, regenerate the form.<p>If a form is somehow resubmitted, print a nice message saying saying that transaction was already submitted.
I google that and this was my third result.<p><a href="http://www.gcflearnfree.org/internetsafety/6/print" rel="nofollow">http://www.gcflearnfree.org/internetsafety/6/print</a><p>Topic 6 talks about it. So simple.
