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.
