NAME    [Toc]    [Back]

       SSL_CTX_flush_sessions,    SSL_flush_sessions   -   Remove
       expired sessions

SYNOPSIS    [Toc]    [Back]

       #include <openssl/ssl.h>

       void SSL_CTX_flush_sessions(
               SSL_CTX *ctx, long tm ); void SSL_flush_sessions(
               SSL_CTX *ctx, long tm );

DESCRIPTION    [Toc]    [Back]

       The SSL_CTX_flush_sessions() function causes a run through
       the  session  cache  of  ctx to remove sessions expired at
       time (tm).

       The SSL_flush_sessions() function is  a  synonym  for  the
       SSL_CTX_flush_sessions() function.

NOTES    [Toc]    [Back]

       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 once they are expired, they  should  be  removed
       from  the cache to save resources. This can be done  automatically
 whenever 255 new sessions are  established  (see
       SSL_CTX_set_session_cache_mode())  or  manually by calling
       the SSL_CTX_flush_sessions() function.

       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.

       The SSL_CTX_flush_sessions() function will only check sessions
  stored  in  the  internal  cache. When a session is
       found and removed, the remove_session_cb is called to synchronize
     with     the     external     cache.     (See
       SSL_CTX_sess_set_get_cb().)
