I might be missing the point here but yes, jifty does emulate
continuations like seaside. As to how they go about it.... not a clue.

There are a few ways that I can think of but all seem some what
clunky. The "best" would be to store a cookie with some 'state_id'
that is then recorded on the backend with all the needed info. Then
when the user requests a page, and since all cookies are avail for all
requests you can rebuild state on the backend and continue as though
nothing has happend. Though to emulate what I saw from last night it
looks like seaside is also adding a unique get var on the URL that
would have the same effect but would give the user the ability to use
the backbutton to change state as well as bookmark but would look some
what ugly and give the user the abitily to monkey with that var.

everything else that I can think of is to just pass everything via
post... though the more that I think about it... I dont think that
would work out so well as the back button would kill it....
