I did a system test on a new ASP.NET app. I encountered several exceptions when using the BACK button in my browser (IE 7).
I stated in a review-record that the web-app must support the use of a BACK button (or at least handle it gracefully with for example session-time out warnings). The teamlead did not agree with me as he stated that a web-app should not support working with the back-button by default.
Do you agree?
