If the session is considered bad, because +L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection +and L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was not used to set the +SSL_SENT_SHUTDOWN state, the session will also be removed +from the session cache as required by RFC2246. + +=head1 RETURN VALUES + +SSL_free() does not provide diagnostic information. + +L<SSL_new(3)|SSL_new(3)>, L<SSL_clear(3)|SSL_clear(3)>, +L<SSL_shutdown(3)|SSL_shutdown(3)>, L<SSL_set_shutdown(3)|SSL_set_shutdown(3)>, +L<ssl(3)|ssl(3)> + +=cut |
