150If enabled, the internal session cache will collect all sessions established
151up to the specified maximum number (see \fISSL_CTX_sess_set_cache_size()\fR).
152As sessions will not be reused ones they are expired, they should be
153removed from the cache to save resources. This can either be done
154 automatically whenever 255 new sessions were established (see
e056f0e0 155\&\fISSL_CTX_set_session_cache_mode\fR\|(3))
e257b235 156or manually by calling \fISSL_CTX_flush_sessions()\fR.

157.PP
158The parameter \fBtm\fR specifies the time which should be used for the
159expiration test, in most cases the actual time given by \fItime\fR\|(0)
160will be used.
161.PP
e056f0e0 162\&\fISSL_CTX_flush_sessions()\fR will only check sessions stored in the internal
984263bc

163cache. When a session is found and removed, the remove_session_cb is however
164called to synchronize with the external cache (see
e056f0e0 165\&\fISSL_CTX_sess_set_get_cb\fR\|(3)).
