This document describes an extension to SIP (RFC 2543) to provide a mechanism for storing state and other information in SIP comparable to the HTTP state mechanisms defined in RFC 2109. This extension includes a new SIP header ('Cookie:'), an option tag for feature negotiation ('cookie') and IANA registration considerations for registering the 'cookie' extension, semantics of the value of the Cookie: header, and behavioral rules for processing these headers by SIP nodes supporting the 'cookie' extension. This document also briefly discusses possible uses of cookies, and security considerations for their use.
