title: IE doesn't download file with jQuery File Download plugin
body: <p>I’m using  jQuery File Download plugin in my java code and work fine with Firefox and Chrome but doesn’t start the download with Internet Explorer.
  I set these headers:</p>
  
  <pre><code>response.setHeader("Set-Cookie", "fileDownload=true; path=/");
  response.setHeader("Content-Disposition","attachment; filename="+file);
  </code></pre>
  
  <p>and in my javascript I use this code:</p>
  
  <pre><code>$.fileDownload(
      "/async/paas/caaas/downloadCertificate/"+serialNumber, 
      {
          successCallback: function (url) {
              //
          },
          failCallback: function (HttpServletResponse, url) {
              $(“#modalDownloadFailedCertificate”).modal("show");
          }
      }
  );
  return false;
  </code></pre>
  
  <p>In IE, with F12 modality, i have this row:</p>
  
  <p>URL: async/paas/caaas/downloadCertificate/591C94<br>
  Metodo: GET (In sospeso...)
  Risultato: (In sospeso...)<br>
  Tipo:   (In sospeso...)
  Ricevuti: 0 B<br>
  Tempo impiegato: (In sospeso...)<br>
  Iniziatore: esplorazione frame</p>
  
  <p>Someone has the same problem?
  Thanks in advance</p>
