Answer 1

You should set header with file size to make progress bar appear. Content-type also should be specified, use application/ocet-stream for unknown mime type (or to force download).

header('Content-Type: application/ocet-stream');
header('Content-Disposition: attachment; filename=test.dat');
header('Content-Length: '.filesize('test.dat'));
header('Content-Description: File Transfer');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
readfile('test.dat');
exit;
