=head1 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 L<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.
|
|
