I posted a proposal for a "State:" header to www-talk back on 2 Feb 1995,
which is substantially similar to what Netscape implemented as cookies in
Netscape 1.1.  So even Netscape could claim prior art, and I don't know
whether an unimplemented proposal for an idea could be prior art to that.  

Is the patent for the idea to embed a session identifier in a URL?
was doing something like that back in 1993, too.
