Answer 1

You don't download the file using AJAX.

You just have to give the URL like but the problem is that you have to force download using headers and URL Rewriting to intercept the requests:

In case of an image:

---

$filename = basename($_GET['img']); // don't accept other directories
$size = @getimagesize($filename);
$fp = @fopen($filename, "rb");
if ($size && $fp)
{
   header("Content-type: {$size['mime']}");
   header("Content-Length: " . filesize($filename));
   header("Content-Disposition: attachment; filename=$filename");
   header('Content-Transfer-Encoding: binary');
   header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
   fpassthru($fp);
   exit;
}

In this case.. the URL will not be changed (I think this is what you want)
