I have kind of the opposite problem of the accepted answer to this question: Ajax, back button and DOM updates
There, most people wanted Firefox to fire "unload" event when coming Back to the page with the Back button.
We manipulate the divs that are shown/hidden (navigating a tree), and go off to another page. When you click "Back", Firefox uses its bfcache and shows the page as it was when you left (this is good). IE shows the page in its initial state (this is bad). We want IE to behave like firefox and use its bfcache, are there any tricks to make it do so?
(we are not using Jquery)
