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 estab-
       lished SSL/TLS sessions in client mode.

       SSL_CTX_sess_connect_renegotiate() returns the number of start renego-
       tiations 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 estab-
       lished SSL/TLS sessions in server mode.

       SSL_CTX_sess_accept_renegotiate() returns the number of start renegoti-
       ations 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.
