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

handshakes in client mode.

SSL_CTX_sess_connect_good() returns the number of successfully established

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

handshakes in server mode.

SSL_CTX_sess_accept_good() returns the number of successfully established

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_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 section.
