<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p><code>SSL_CTX_flush_sessions()</code> causes a run through the session cache of
|
|
<strong>ctx</strong> to remove sessions expired at time <strong>tm</strong>.</p>
|
|
<p>
|
|
</p>
|
|

|
<h1><a name="notes">NOTES</a></h1>
|
|
<p>If enabled, the internal session cache will collect all sessions established
|
|
up to the specified maximum number (see SSL_CTX_sess_set_cache_size()).
|
|
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
|
|
<em>SSL_CTX_set_session_cache_mode(3)</em>)
|
|
or manually by calling <code>SSL_CTX_flush_sessions()</code>.</p>
|
|
<p>The parameter <strong>tm</strong> specifies the time which should be used for the
|
|
expiration test, in most cases the actual time given by <code>time(0)</code>
|
|
will be used.</p>
|
|
<p><code>SSL_CTX_flush_sessions()</code> 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
|
|
<em>SSL_CTX_sess_set_get_cb(3)</em>).</p>
