It's a bird. It's a plane. No, it's the invisible inline frame!

There's some test code:

test.php:

<html>
<body>
<p>The download will start now!</p>
<iframe src="test2.php?query=<?=$query?>" style="display: none"></iframe>
<p>Something something...</p>
</body>
</html>

 test2.php:

<?

header("Content-type: application/octet-stream");
header("Content-disposition: attachment; filename=\"testing.txt\"");

echo str_repeat("Hello world\n", 1000);

?>
