title: downloading csv file using dojo xhrget
body: <p>i have a csv file in my local which i try to return as response using a servlet. i call this servlet using dojo, but it seems it doesnt want to download it. i have set the response headers to "Content-Disposition" and attachment; filename=myfile, but it doesn't allow the file save as dialog to appear.</p>
  
  <p>i think i read somewhere that dojo doesn't allow the file save dialog box to appear.</p>
