The data are stored in both places.  You are in fact stipulating that
it's not a cookie (in your terms) either in transit or when it is stored
on the server.

OK.  That's one point of view but then you can't say things like "a
cookie is sent to the server in the HTTP request header".  The cookie
ceases to be a cookie once in transmission.  I think that just
complicates the way have to talk about these things.

I think that's unnecessarily fussy and does not match the usage in the
RFCs.  They refer to "sending cookies" and the one specifically about
cookies defines them as a name/value pairs that are passed to the user
agent and returned to the server.
