Hi,

I've got a file download script that is working perfectly when issued with a GET request. However when it is issued with a HEAD request it leaves the Content-Length header out, even though I explicitly set it.

I think I'm going insane. The HEAD request is needed to allow compatibility with a P2P service we want to support for our downloaders, but I feel I'm at an impass.

This is a small excert from the download script..

require_once($DOCUMENT_ROOT."includes/ff_files.class.php");
$file = new ff_file($f, "viewhash", false, $db_link);


if ($_SERVER['REQUEST_METHOD'] == 'HEAD') {
    ob_start();
    $filename = $file->location.$file->name;
    $filesize = filesize($filename);
     if ($file->version == 3)
         $display_filename = $file->display_name;
     else
         $display_filename = $file->name;

     header('Content-Description: File Transfer');
    header('Content-Type: application/force-download');
    header("Content-Length: $filesize");
    header('Content-Disposition: attachment; filename=' .basename($display_filename));
    mysql_close($db_link);
    ob_flush();
    exit();

}

Here is the dump from a telnet session..

[root@xx ~]# telnet xxx.xxxxxx.com 80
