This has happened to me a couple of times already and it’s very annoying. I’ve left a thread open, gone for a couple of hours and then replied to the thread. But, what happens is I get a simple message about a mismatched security token. The page is a simple error page, with nothing to indicate it’s Sitepoint. I press the back button, and of course the textarea is empty (FF3.5). I suppose this is because of its rich text capabilities rather than FF’s fault.
Surely it must be possible to somehow save the user’s input? Even if it’s just a part of the error message so they can at least copy it (“here’s what you submitted”). This sort of thing also happens if you press the edit button and take a long time to write your answer, during which the threshold time for editing posts has passed. Except in this case, there’s no error message, your edits just vanish into thin air. It seems obvious the user should be warned the time has passed and that (s)he’s be better off writing a new post, with the opportunity to copy over their writing.
Can this be remedied please?
