Force download

Hej.

Har dette script, som har virket før, men efter at have skiftet server, virker det ikke mere. Får blot fejlen "The file is not avaliable for download". Er der nogen, der umiddelbart kan se hvad der er i vejen?

Scriptet:

<?php
/*******************************************************************
* Save this script as download.php
* Usage: download.php?filename=name_of_file.extension
********************************************************************/
$shortname = basename( $filename );

if( file_exists( $filename )          // sanity check
    && !eregi( "p?html?", $filename ) // security check
    && !eregi( "inc", $filename )
    && !eregi( "php3?", $filename ) ){
  $size = filesize( $filename );
  header("Expires: 0");
  header("Content-Transfer-Encoding: binary");
  header("Cache-Control: no-cache, must-revalidate");
  header("Pragma: no-cache");
  header("Content-Type: application/save");
  header("Content-Disposition: attachment; filename=$shortname");
  $fh = readfile("$filename");
    fpassthru($fh);
   
  exit;
} else {
print "The file $shortname is not available for download";
}
?>

Mvh.
