before event_route[websocket:closed] is run, i can assign id of the closed ws connection to rcv.proto_reserved1 field of the faked message: static void wsconn_run_route(ws_connection_t *wsc) { ... fmsg = faked_msg_next(); wsc->rcv.proto_reserved1 = wsc->id; fmsg->rcv = wsc->rcv; ... } the problem is that int pv_get_tcpconn_id(struct sip_msg *msg, pv_param_t *param, pv_value_t *res) calls tcpconn_get: if ((con = tcpconn_get(msg->rcv.proto_reserved1, 0, 0, 0, 0)) == NULL) return pv_get_null(msg, param, res); and since the ws connection whose id is stored in msg->rcv.proto_reserved1 does not anymore exist, the statement returns null pv value. is there some way to figure out that $conid was accessed from event_route[websocket:closed] in which case the connection id stored in msg->rcv.proto_reserved1 should be returned without checking if that connection still exists? if not, i guess i need to introduce yet another pv for the purpose. -- juha
