156 .IX Header "DESCRIPTION"
157 \&\fISSL_CTX_sess_number()\fR returns the current number of sessions in the internal
160 \&\fISSL_CTX_sess_connect()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
163 \&\fISSL_CTX_sess_connect_good()\fR returns the number of successfully established
164 \&\s-1SSL/TLS\s0 sessions in client mode.
166 \&\fISSL_CTX_sess_connect_renegotiate()\fR returns the number of start renegotiations
169 \&\fISSL_CTX_sess_accept()\fR returns the number of started \s-1SSL/TLS\s0 handshakes in
172 \&\fISSL_CTX_sess_accept_good()\fR returns the number of successfully established
173 \&\s-1SSL/TLS\s0 sessions in server mode.
175 \&\fISSL_CTX_sess_accept_renegotiate()\fR returns the number of start renegotiations
178 \&\fISSL_CTX_sess_hits()\fR returns the number of successfully reused sessions.
179 In client mode a session set with \fISSL_set_session\fR\|(3)
180 successfully reused is counted as a hit. In server mode a session successfully
181 retrieved from internal or external cache is counted as a hit.
183 \&\fISSL_CTX_sess_cb_hits()\fR returns the number of successfully retrieved sessions
184 from the external session cache in server mode.
186 \&\fISSL_CTX_sess_misses()\fR returns the number of sessions proposed by clients
187 that were not found in the internal session cache in server mode.
189 \&\fISSL_CTX_sess_timeouts()\fR returns the number of sessions proposed by clients
190 and either found in the internal or external session cache in server mode,
191 but that were invalid due to timeout. These sessions are not included in
192 the \fISSL_CTX_sess_hits()\fR count.
194 \&\fISSL_CTX_sess_cache_full()\fR returns the number of sessions that were removed
195 because the maximum session cache size was exceeded.
