147\&\fISSL_CTX_flush_sessions()\fR causes a run through the session cache of

153If enabled, the internal session cache will collect all sessions established
154up to the specified maximum number (see \fISSL_CTX_sess_set_cache_size()\fR).
155As sessions will not be reused ones they are expired, they should be
156removed from the cache to save resources. This can either be done
157 automatically whenever 255 new sessions were established (see
e056f0e0 158\&\fISSL_CTX_set_session_cache_mode\fR\|(3))
aac4ff6f 159or manually by calling \fISSL_CTX_flush_sessions()\fR.

160.PP
161The parameter \fBtm\fR specifies the time which should be used for the
162expiration test, in most cases the actual time given by \fItime\fR\|(0)
163will be used.
164.PP
e056f0e0 165\&\fISSL_CTX_flush_sessions()\fR will only check sessions stored in the internal
984263bc

166cache. When a session is found and removed, the remove_session_cb is however
167called to synchronize with the external cache (see
e056f0e0 168\&\fISSL_CTX_sess_set_get_cb\fR\|(3)).
