161 .IX Header "DESCRIPTION"
162 \&\fISSL_CTX_sess_number()\fR returns the current number of sessions in the internal
165 \&\fISSL_CTX_sess_connect()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
168 \&\fISSL_CTX_sess_connect_good()\fR returns the number of successfully established
169 \&\s-1SSL/TLS\s0 sessions in client mode.
171 \&\fISSL_CTX_sess_connect_renegotiate()\fR returns the number of start renegotiations
174 \&\fISSL_CTX_sess_accept()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
177 \&\fISSL_CTX_sess_accept_good()\fR returns the number of successfully established
178 \&\s-1SSL/TLS\s0 sessions in server mode.
180 \&\fISSL_CTX_sess_accept_renegotiate()\fR returns the number of start renegotiations
183 \&\fISSL_CTX_sess_hits()\fR returns the number of successfully reused sessions.
184 In client mode a session set with \fISSL_set_session\fR\|(3)
185 successfully reused is counted as a hit. In server mode a session successfully
186 retrieved from internal or external cache is counted as a hit.
188 \&\fISSL_CTX_sess_cb_hits()\fR returns the number of successfully retrieved sessions
189 from the external session cache in server mode.
191 \&\fISSL_CTX_sess_misses()\fR returns the number of sessions proposed by clients
192 that were not found in the internal session cache in server mode.
194 \&\fISSL_CTX_sess_timeouts()\fR returns the number of sessions proposed by clients
195 and either found in the internal or external session cache in server mode,
196 but that were invalid due to timeout. These sessions are not included in
197 the \fISSL_CTX_sess_hits()\fR count.
199 \&\fISSL_CTX_sess_cache_full()\fR returns the number of sessions that were removed
200 because the maximum session cache size was exceeded.
