[PHP] header gives different results with post

[Ellen Cyran]

When I submit a post to the following page rather than a get
the download screen in IE 5.5SP2 appears twice. Is there
any way around this? I definitely need to use post since the
length of the string being sent is fairly long.

<?php

header("Content-type: application/octet-stream");
header('Content-Disposition: attachment;filename="results.csv"');// Try to name the output file
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: '.gmdate("D, d M Y H:i:s").' GMT'); // always modified
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0
/*$nocache = 'Cache-Control: no-cache'; */ // HTTP/1.1
//header($nocache);
header('Content-Transfer-Encoding: binary'); // Binary data

echo "test";

?>

Thanks.
