984263bc

207If enabled, the internal session cache will collect all sessions established
208up to the specified maximum number (see \fISSL_CTX_sess_set_cache_size()\fR).
209As sessions will not be reused ones they are expired, they should be
210removed from the cache to save resources. This can either be done
211 automatically whenever 255 new sessions were established (see
212SSL_CTX_set_session_cache_mode(3))
213or manually by calling \fISSL_CTX_flush_sessions()\fR.
214.PP
215The parameter \fBtm\fR specifies the time which should be used for the
216expiration test, in most cases the actual time given by \fItime\fR\|(0)
217will be used.
218.PP
a7d27d5a 219\fISSL_CTX_flush_sessions()\fR will only check sessions stored in the internal
984263bc
MD
220cache. When a session is found and removed, the remove_session_cb is however
221called to synchronize with the external cache (see
222SSL_CTX_sess_set_get_cb(3)).
