DESCRIPTION
The SSL_CTX_sess_number() function returns the current number of ses‐
sions 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 success‐
fully 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 success‐
fully 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_ses‐
sion() 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 pro‐
posed 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 ses‐
sion 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
