[ciapug] fpassthru file download

[John Rearick]

The following code seems to work in IE 6.  There are also a lot of  
comments at the readfile page http://us2.php.net/manual/en/ 
function.readfile.php

header("Content-type: application/force-download");
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($file));
header("Content-disposition: attachment; filename=\"".$name."\"");

readfile($file);
