158If enabled, the internal session cache will collect all sessions established
159up to the specified maximum number (see \fISSL_CTX_sess_set_cache_size()\fR).
160As sessions will not be reused ones they are expired, they should be
161removed from the cache to save resources. This can either be done
162 automatically whenever 255 new sessions were established (see
e056f0e0 163\&\fISSL_CTX_set_session_cache_mode\fR\|(3))
e257b235 164or manually by calling \fISSL_CTX_flush_sessions()\fR.
984263bc

165.PP
166The parameter \fBtm\fR specifies the time which should be used for the
167expiration test, in most cases the actual time given by \fItime\fR\|(0)
168will be used.
169.PP
e056f0e0 170\&\fISSL_CTX_flush_sessions()\fR will only check sessions stored in the internal

171cache. When a session is found and removed, the remove_session_cb is however
172called to synchronize with the external cache (see
e056f0e0 173\&\fISSL_CTX_sess_set_get_cb\fR\|(3)).
