jQuery does not support .Post() in IE

jQuery does not support .Post() in IE

Hello,
I have the follow code:
  1.  <script src="jquery.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function(){
                $("#Buscar").click(function (e) {
                 e.preventDefault();
                 $("#resultado").html("Cargando... <img alt='cargando' id='loader'  src='http://148.232.110.91/Embarques/loader.gif' />");
                
                   $.post("Controlador.ashx",
                    {
                    
                     // cmbReportType:$("#cmbReportType").val(),
                      Remision:$("#Remision").val(),
                      //CmbCentro:$("#CmbCentro").val(),
                      //CmbCliente:$("#CmbCliente").val(),

                    },
                    function(data,status){
                       
                    }).done(function(data) { $("#resultado").html(data); });
                });
            });
    function Buscar_onclick() {

    }


























This code does work very well if I call the function from IE but from: http://localhost/Page/Index.html But if I try to call my function from: http://192.68.1.1/Page/Index.html <-- does not work!! But if I use Firefox, my code does work, very well... Qustion... ¿does IE not supports .Post()?
