\&\fISSL_CTX_flush_sessions()\fR causes a run through the session cache of
|
|
\&\fBctx\fR to remove sessions expired at time \fBtm\fR.

|

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