Hi, Mark,

So if a request contains a list of URIs and the server needs to deference
all the URIs in order to process this request, would you consider this
stateful?

I originally had a "What is state" question there, but the best answer I
could come up with was "data", so I removed it.  I note that yours says
much the same thing 8-)... though perhaps carries some redundancy with
"belonging to the stateful entity").

But please, feel free to edit it yourself.  That's why I put it on a
Wiki!

Mark.
