latest apache2, Windows 2000 server, php 5.0.0/5.0.1/5.0.2-cvs.. same
problem with all these configurations. When streaming files > 5mb thru
php there is timeouts. Also, it seems not to work to stream these files
over a slower connections (0.5mbit) at all (stops after a few seconds)
when it works better on a 100mbit lan.

Description:
------------
Attempting to use readfile() to send large (over 250MB) binary objects
causes PHP 5.0.1 to hang or the web server to send a 302 error.
Reverting back to PHP 4.3.8 resolves the issue.
Using fopen() and fpassthru() only makes the issue worse.
We are using IIS 6 and the PHP ISAPI script engine.
Reproduce code:
---------------
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment;
filename=".basename($filename).";");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($filename));
readfile("$filename");
exit();
Expected result:
----------------
PHP 5 has an issue with sending large binary files. This should be
resolved.
