| 28The ssl session has reference counts from two users: the SSL object, for 29which the reference count is removed by SSL_free() and the internal 30session cache. If the session is considered bad, because 31L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection 32and L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was not used to set the 33SSL_SENT_SHUTDOWN state, the session will also be removed 34from the session cache as required by RFC2246. 35
