Thanks for asking that question, Mike. It's why I've found that
there's not as much enlightenment as you'd think in looking at the
problem that way.

Yes, the shopping cart is resource state, but it's also
session/application state in the context of that final purchase
message.

When you think about it, *any* state can be given a URI, but doing so
doesn't un-make it session state if its being used that way.
