title: Jquery getJSON cach issue?
body: <p>I'm using getJSON to get data from a WCF. The app works for a few times and after that it seems to get data from cache. The problem occures ion Firefox, Chrome. In internet explorer 9 i can't get any of the data.</p>
  
  <pre><code>function get_WCF() {
              $.ajaxSetup({ cache: false });
              $.getJSON('http://192.168.1.8:9100/PraticaService.svc/GetAllQueries', {
                  idPratica : $("#txtIdPratica").val() + "M"
              }, function(json) {
                  json = jQuery.parseJSON(json.d.GetAllQueries);
                  if(json.$values[0].$values[0]) {
                      $('#txtCognomeRagioneSociale').val(json.$values[3].$values[0].DENOMINAZIONE);}
              })
          };
