DESCRIPTION
SSL_CTX_sess_number(3) 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 started
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 started
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 DESCRIPTION section.
