Hi i am working on a server sent event script to be sent when the user has logged out, but in the network tab the server sent pages are being sent every couple of seconds with no data.

Client-Side script

var source=new EventSource("include/updates.php");

        source.addEventListener('logout',function(event){
            $("#notificationsContainer").append(event.data + "<br />");
            source.close();
        },false);

Server-side script

header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');


if(!isset($_SESSION))
    session_start();

if(!isset($_SESSION['id']))
{
    $time = date('r');
    echo "event: logout\n";
    echo "data: user logged out at {$time}\n\n";
    flush();
}

Thanks for your time,
