I'd say the backbutton is as useful for POST as it is for GET. It's a navigation tool and sometimes the best way to get where you want is to go back two steps and forward in another direction. Mind you, it's still more complicated to handle actions (POST) is a safe manner. The back button doesn't undo and if you go forward the same way, you may trigger a duplicate action. It's up to the application to handle such cases. I think this is applicable to the wizard stuff too. I think back button support would be a very nice usability enhancement there. alex -- You received this message because you are subscribed to the Google Groups "Lift" group.
