A strategy for integrating this into the session-tracking stuff would be:
1. Write all of your code to use the session tracking API.
2. Pass separate state info in the URL like you're doing now.
3. Copy the URL state into the current session on every request.
This is probably not very desirable for you Toby, especially as you already
have something working! ;-) The session tracking stuff doesn't buy you
very much. I'd be interested, however, to get a strategy down in writing
for using the session tracking stuff to do what you're doing, as it's very

Ive been doing something similar for a while, which I know Ive
mentioned to Chris before, but I think this was before Andy joined the
Im storing session-like data pickled inside the URL. I end up with
long, ugly-looking URLs, but it does mean that a browser's bookmarks
and back button work as expected, effectively 'undoing' changes made
to thier session state.
This solution also avoids the problem of finding enough storage on the
server to store multiple revisions of each session.
At the moment this isnt based on 2.3.0's session support. I havent yet
looked at that and dont know how well it would integrate, although I
do hope to do that at some time.
