Interesting, thanks. I stand corrected on the history part. But routing is still left to the user (its even explicitly mentioned in the doc you linked to. For example if a user clicks a link in their email to /movies/2001, it does not know to show the movies frame with the 2001 content. We have to implement some kind of url parsing to determine what divs need updating and then update those on first page load.
