How to use HTTP/2 connection instead of session cookies?

Question

is it possible to use HTTP/2 connection (TCP session) for session tracking, instead of session cookies (this will help when cookies are disabled)?

HTTP/2 was published 2015-05-14 (RFC 7540)

HTTP/2 was enabled by default in FF from 2015-01-13 (v35).

List of HTTP/2-server implementations (http2-katana, etc)

Answer 1

HTTP/2 connections are long lived, but not persistent; an H2 connection can go away and die at any time. And this is the internet, TCP connections can be torn down for no apparent reasons :-). If you requirements for HTTP session handling can deal with that, then yeah, you can likely just use your (one) H2 connection as a session "cookie". It would be very unreliable and unpredictable at best.
