Though it would be very nice to have defined semantics wrt the unload handler, I always thought this work could be done with the beforeonunload handler, instead. As far as the unload handler question, what are the semantics for XHR? Seems the application of "saving some application state via I/O" is the same concept here, so the same rules should apply. ~Brady On Feb 8, 2008, at 1:44 AM, Alexey Proskuryakov wrote: > > It seems to be a natural idea to save Web application state from an > unload event handler.
