DESCRIPTION

       SSL_CTX_sess_number() returns the current number of sessions in the internal session
       cache.

       SSL_CTX_sess_connect() returns the number of started SSL/TLS handshakes in client mode.

       SSL_CTX_sess_connect_good() returns the number of successfully established SSL/TLS
       sessions in client mode.

       SSL_CTX_sess_connect_renegotiate() returns the number of started renegotiations in client
       mode.

       SSL_CTX_sess_accept() returns the number of started SSL/TLS handshakes in server mode.

       SSL_CTX_sess_accept_good() returns the number of successfully established SSL/TLS sessions
       in server mode.

       SSL_CTX_sess_accept_renegotiate() returns the number of started renegotiations in server
       mode.

       SSL_CTX_sess_hits() returns the number of successfully reused sessions.  In client mode a
       session set with SSL_set_session(3) successfully reused is counted as a hit. In server
       mode a session successfully retrieved from internal or external cache is counted as a hit.

       SSL_CTX_sess_cb_hits() returns the number of successfully retrieved sessions from the
       external session cache in server mode.

       SSL_CTX_sess_misses() returns the number of sessions proposed by clients that were not
       found in the internal session cache in server mode.

       SSL_CTX_sess_timeouts() returns the number of sessions proposed by clients and either
       found in the internal or external session cache in server mode,
        but that were invalid due to timeout. These sessions are not included in the
       SSL_CTX_sess_hits() count.

       SSL_CTX_sess_cache_full() returns the number of sessions that were removed because the
       maximum session cache size was exceeded.

RETURN VALUES

       The functions return the values indicated in the DESCRIPTION section.
