-Subject: [PATCH] net/http, net/ftp: fix session resumption with TLS 1.3
-
-When TLS 1.3 is in use, the session ticket may not have been sent yet
-even though a handshake has finished. Also, the ticket could change if
-multiple session ticket messages are sent by the server. Use
-SSLContext#session_new_cb instead of calling SSLSocket#session
-immediately after a handshake. This way also works with earlier protocol
-versions.
