DESCRIPTION

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

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

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

  The SSL_CTX_sess_connect_renegotiate() function returns the number of start
  renegotiations in client mode.

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

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

  The SSL_CTX_sess_accept_renegotiate() function returns the number of start
  renegotiations in server mode.

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

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

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

  The SSL_CTX_sess_timeouts() function 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.

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


RETURN VALUES

  See the Description section.
