Facebook bottom bar state

Question

What's the best way to keep state in a bottom bar that sticks to the UI, even when different pages are navigated to? Let's say I was programming Facebook and wanted to keep all open conversations the same, etc with the most efficiency. I could use something like jixedbar (is there a better solution?) for the bar, but not sure how to keep state best.

Thanks!

Answer 1

If you wanted to implement something like Facebook Chat in the bottom bar, just read how they did it. A lot of what they use is open source (i.e. Thrift). http://www.facebook.com/note.php?note_id=14218138919 http://www.scribd.com/doc/22428456/Erlang-at-Facebook

Answer 2

The easiest way is to use session cookies so it can be printed again in the same state.
