DESCRIPTION

30       SSL_CTX_sess_number() returns the current number of sessions in the
31       internal session cache.
32
33       SSL_CTX_sess_connect() returns the number of started SSL/TLS handshakes
34       in client mode.
35
36       SSL_CTX_sess_connect_good() returns the number of successfully
37       established SSL/TLS sessions in client mode.
38
39       SSL_CTX_sess_connect_renegotiate() returns the number of start
40       renegotiations in client mode.
41
42       SSL_CTX_sess_accept() returns the number of started SSL/TLS handshakes
43       in server mode.
44
45       SSL_CTX_sess_accept_good() returns the number of successfully
46       established SSL/TLS sessions in server mode.
47
48       SSL_CTX_sess_accept_renegotiate() returns the number of start
49       renegotiations in server mode.
50
51       SSL_CTX_sess_hits() returns the number of successfully reused sessions.
52       In client mode a session set with SSL_set_session(3) successfully
53       reused is counted as a hit. In server mode a session successfully
54       retrieved from internal or external cache is counted as a hit.
55
56       SSL_CTX_sess_cb_hits() returns the number of successfully retrieved
57       sessions from the external session cache in server mode.
58
59       SSL_CTX_sess_misses() returns the number of sessions proposed by
60       clients that were not found in the internal session cache in server
61       mode.
62
63       SSL_CTX_sess_timeouts() returns the number of sessions proposed by
64       clients and either found in the internal or external session cache in
65       server mode,
66        but that were invalid due to timeout. These sessions are not included
67       in the SSL_CTX_sess_hits() count.
68
69       SSL_CTX_sess_cache_full() returns the number of sessions that were
70       removed because the maximum session cache size was exceeded.
