166 .IX Header "DESCRIPTION"
167 \&\fISSL_CTX_sess_number()\fR returns the current number of sessions in the internal
170 \&\fISSL_CTX_sess_connect()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
173 \&\fISSL_CTX_sess_connect_good()\fR returns the number of successfully established
174 \&\s-1SSL/TLS\s0 sessions in client mode.
176 \&\fISSL_CTX_sess_connect_renegotiate()\fR returns the number of start renegotiations
179 \&\fISSL_CTX_sess_accept()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
182 \&\fISSL_CTX_sess_accept_good()\fR returns the number of successfully established
183 \&\s-1SSL/TLS\s0 sessions in server mode.
185 \&\fISSL_CTX_sess_accept_renegotiate()\fR returns the number of start renegotiations
188 \&\fISSL_CTX_sess_hits()\fR returns the number of successfully reused sessions.
189 In client mode a session set with \fISSL_set_session\fR\|(3)
190 successfully reused is counted as a hit. In server mode a session successfully
191 retrieved from internal or external cache is counted as a hit.
193 \&\fISSL_CTX_sess_cb_hits()\fR returns the number of successfully retrieved sessions
194 from the external session cache in server mode.
196 \&\fISSL_CTX_sess_misses()\fR returns the number of sessions proposed by clients
197 that were not found in the internal session cache in server mode.
199 \&\fISSL_CTX_sess_timeouts()\fR returns the number of sessions proposed by clients
200 and either found in the internal or external session cache in server mode,
201 but that were invalid due to timeout. These sessions are not included in
202 the \fISSL_CTX_sess_hits()\fR count.
204 \&\fISSL_CTX_sess_cache_full()\fR returns the number of sessions that were removed
205 because the maximum session cache size was exceeded.
