Use Ethereal or your own tracer to find out! And compare to a direct request
to a real file!
AFAIK the headers sent here are:
'Content-Type' => 'application/x-octetstream', (perhaps other)
'Cache-Control' => 'public',
'Accept-Ranges' => 'bytes',
'Connection' => 'close'

Did you try something like this:
<?php
header("Content-Type: application/pdf");
header("Content-Disposition: inline; filename=foo.pdf");
header("Accept-Ranges: bytes");
header("Content-Length: $len");
header("Expires: 0");
header("Cache-Control: private");
// header("Pragma: no-cache");//don't send this header!!
?>
What headers are sent at this moment? Could you post them?

If you send the same headers and the same data - there _can_not_ be any
difference. How should your client recognize any difference? There _must_ be
a difference! Use a very small file to test it, so you can compare the whole
HTTP-Header + Body easily.

Oh, I could not know ;-)
