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
     start 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
     start 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_number(3)       OpenSSL       SSL_CTX_sess_number(3)

     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.
