OpenSSL SSL_CTX_flush_sessions(3openssl) 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(). ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+--------------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+--------------------------+ |Availability | library/security/openssl | +---------------+--------------------------+ |Stability | Pass-through uncommitted | +---------------+--------------------------+ 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)).
