 The ssl session contains all information required to re-establish the
-connection without a full handshake for SSL versions <= TLSv1.2. In TLSv1.3 the
-same is true, but sessions are established after the main handshake has occurred.
-The server will send the session information to the client at a time of its
-choosing which may be some while after the initial connection is established (or
-not at all). Calling these functions on the client side in TLSv1.3 before the
-session has been established will still return an SSL_SESSION object but it
-cannot be used for resuming the session. See L<SSL_SESSION_is_resumable(3)> for
-information on how to determine whether an SSL_SESSION object can be used for
-resumption or not.

-Additionally, in TLSv1.3, a server can send multiple session messages for a
-single connection. In that case the above functions will only return information
-on the last session that was received.

 The preferred way for applications to obtain a resumable SSL_SESSION object is
 to use a new session callback as described in L<SSL_CTX_sess_set_new_cb(3)>.
