=head1 NAME
|
|
|
|
SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired sessions
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
|
|
void SSL_flush_sessions(SSL_CTX *ctx, long tm);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_CTX_flush_sessions() causes a run through the session cache of
|
|
B<ctx> to remove sessions expired at time B<tm>.
|
|
|
|
SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().
|
|
|
|
=head1 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
|
|
L<SSL_CTX_set_session_cache_mode(3)>)
|
|
or manually by calling SSL_CTX_flush_sessions().
|
|
|
|
The parameter B<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
|
|
L<SSL_CTX_sess_set_get_cb(3)>).
