	id := ctx.PathValue("id")
	if p, err := preauth.Load(id); err != nil {
		err_msg := "err:@preAuth load: " + err.Error()
		logger.Error(err_msg)
		responder.RespondWithError(ctx, 500, err_msg)
		return
	} else {
		if n, err := node.LoadUnauth(p.NodeId); err == nil {
			switch p.Type {
			case "download":
