Multiple parallel request is not handled by server

I am trying to get the progress of a controller method. I have used setInterval method to call the progress method inside the controller but the ajax call inside the setInterval only hits the controller after the execution of controller method and till that time the ajax requests status keeps pending on browser network tab.

I have considered making first method asynchronous

Java Script code

function Import() {
    $('.loader').show();

    var checked;
    if ($('#chkNewCycle').is(":checked")) {
        checked = 'on';
    }
    else {
        checked = 'off';
    }

    var NewCycle = { IsNewCycle: checked };

    $.ajax({
        url: '/DataImport/Import',
        type: 'POST',
        data: NewCycle,
        success: function (result) {
            $('.loader').hide();
            if (result == "success") {
                window.clearInterval(intervalId);
                alert("Imported file for processing.");
                ClearData();

            }
            else {
                alert(result);
            }
        }
    });   


    var intervalId = window.setInterval(function () {
        $.getJSON('/DataImport/GetProgress', function (json) {
            console.log(json.Progress);
            $('#progress').html(json.Progress + '%');
        });
    }, 2000);



}

controller.cs

public async Task<string> Import(string IsNewCycle)
{
/*Some Code*/

await Task.Run(() => { 
/*Some Code*/

int iProgress =Convert.ToInt32(dProgress * 100);
HttpContext.Application["Progress" ] = iProgress;

 });

return string;


}

public ActionResult GetProgress()
{
return Json(new
{
     Progress = HttpContext.Application["Progress"]
}, JsonRequestBehavior.AllowGet);
}

I need to get both the controller method hit simultaneously

Decorate your controller with [SessionState(SessionStateBehavior.ReadOnly)] attribute, then you can execute requests in parallel.
