> This document specifies a way to create a stateful session with Hypertext Transfer Protocol (HTTP) requests and responses. It describes three new headers, Cookie, Cookie2, and Set-Cookie2, which carry state information between participating origin servers and user agents. The method described here differs from Netscape's Cookie proposal [Netscape], but it can interoperate with HTTP/1.0 user agents that use Netscape's method. (See the HISTORICAL section.)

RFC 2965, make of it what you want but I agree with you. Actually, RFC 2109 is even older (1997) and says more or less the same.
