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 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.
