$.ajax({
    url : "/platform/post-tracking/",
    type : "POST",
    async: true,
    data : {
        account : 229829623,

            session = TrackedSession()
            session.account = temp.account
            session.trackedIp = trackingip

    response_data = "Success"
    return HttpResponse(
