security - Can we implement Web session management relying on HTTPS protocol -


webserver provide explicit session management http protocol stateless. suppose if writing new web server , know support https can rely on https session management?

probably not.

requiring stable ssl/tls session identifier (ssl_session_id) essential functionality break site many real users. ssl clients aren't mandated keep same on extended period of time, , browsers may not. believe ie<8 can drop connection , negotiate new session arbitrarily.

there operational concerns... example it'll break if host behind terminating reverse proxy, , you'd have careful caching there no vary:-on-ssl-session-id possible.

it has interesting potential tracking , risk rating part of wider system, i've seen of people who've tried (which not include me, take pinch of salt) it's not reliable replacement cookies today.
