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)).
