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.
