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_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.
