Ajax请求监视流程

Question

I have an AJAX Request in a javascript script where i GET a file like that:

 $.ajax({
      type: "GET",
      url: "./" + img_type + ".bmp",
      dataType: "html",
  timeout: test_timeout, 
      cache: false, 
      success: function(msg)
      {
      //some stuff
      }
  });

the code itself is correct and works perfectly. Is there a way to know HOW much of the file I've downloaded while the request is still ongoing?? I mean, once the request gives to me the success message I know that I've downloaded the entire file, but what if I want to know after two seconds of beginning?? thanks!
