[webkit-dev] Does webkit hold previous loaded pages in memory

As far as i know it does not store any data persistently unless you
plan to save it. It does have sqlite integrated but not really used
that part of webkit,

As far as DOM/Render Tree are concerned i think they are modified each
time new page is loaded. If u are talking for previous sites ( i take
it as previously browsed site), their reference would be
there in Back and forward history object list. Webkit does have memory
based cache. To make it persistent becomes client implementation task.
I think there is no point storing DOM/Render Tree/Javascript related
stuff for history items

Thanks & Regards
