 * Example of download.php:

  <?php
   
  if (file_exists("/{$_GET['file']}"))
  {
    $filesize=filesize("/{$_GET['file']}");
    $file=basename("/{$_GET['file']}");

    header("Content-Type: application/x-kcachegrind");
    header("Content-Disposition: attachment; filename=\"cachegrind.out\"");
    header("Content-Length: {$filesize}");
    passthru("cat /tmp/xdebug/{$file}",$err);
  }

  exit;
