NAME
SSL_CTX_flush_sessions,
SSL_flush_sessions —
remove expired sessions
SYNOPSIS
#include
<openssl/ssl.h>
void
SSL_CTX_flush_sessions(SSL_CTX
*ctx, long tm);
void
SSL_flush_sessions(SSL_CTX
*ctx, long tm);
DESCRIPTION
SSL_CTX_flush_sessions()
causes a run through the session cache of ctx to
remove sessions expired at time tm.
SSL_flush_sessions()
is a synonym for SSL_CTX_flush_sessions().
NOTES
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
SSL_CTX_set_session_cache_mode(3)) or manually by calling
SSL_CTX_flush_sessions().
The parameter tm specifies the
time which should be used for the expiration test, in most cases the actual
time given by
time(0)
will be used.
SSL_CTX_flush_sessions()
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)).
