I wanted to ask a question from my iPod Touch on SO and did some research (looking for links) on the fly, in a new site in Safari. Sadly, Safari got this annoying 'feature' to reload an open site if you dare to ignore it for five minutes (exaggeration).
Now I thought 'Okay, not that much of a problem, I got that neat question auto-saving on SO'. Well, at least that's what I thought. After the 'Ask a question' page finished reloading, I found my nearly finished question to be nuked from existence.
So, does the mobile version not have that feature or was I just unlucky? If it does not have that feature, would it be possible to implement it?
