UniTimer

[picyka]

I have a team that checks every 5 minutes to see if there is any task to display on the screen.
These timers are dangerous to use because the session may not expire.
Is there any way to take care of this? Another situation, the ChainMode property from my research, this option checked only runs the timer if there is no event being processed, would that be it?
Would it be good to use it in these situations?

1. Try to use UniThreadTimer on Server side 

2. You can add extra functions to check if user is online and if is not then close session :

@Sherzod Do you have any tips for this?

function hasTask(host, token) {

    try {

        var Http = new XMLHttpRequest();

        Http.open("GET", host, false);

        Http.setRequestHeader('Authorization', 'Bearer ' + token);

        Http.send();

        if (Http.status == 200) {

            console.log('Buscado tarefa...');

            if (Http.responseText.includes("true")) {

                top.ajaxRequest(top.MainForm.form, '_task', ['value=true']);

            }

        }

    } catch (err) {
        console.log('Erro Tarefa:' + err);
    }
};

procedure TUniMainModule.ExecuteTimerTarefa;
begin
  {180000 - 3 MINUTOS}
  try
    var lUrl := Self.URL_EX_API + 'END POINT';
    var lJsString := 'var TimerTarefa = setInterval(function () {hasTask(' + QuotedStr(lUrl) + ',' + QuotedStr(Self.TOKEN_API) + ');}, 180000);';
    UniSession.JSCode(lJsString);
  except
    on E: Exception do
      TMessageUtils.Error(E.Message);
  end;

procedure TMainForm.UniFormAjaxEvent(Sender: TComponent; EventName: string; Params: TUniStrings);
begin
  if SameStr(EventName, '_task') then
  begin
    TToastUtils.Aviso('Tarefa encontrada, ja vou te mostrar!', False, 'Aviso de Tarefa',8000);
    UniTimerTarefas.Enabled := True;
  end;
end;

I will post here my solution, as I use API it became easier to solve.
Ajax only fires when it's really needed.
