function httpbl_boot() {

  // Only continue when checks are enabled
  if (variable_get('httpbl_check', HTTPBL_CHECK_NONE) != HTTPBL_CHECK_ALL) {
    return;
  }
  $result = httpbl_check();

      if ($_GET['q'] == 'httpbl/whitelist') {
        return;
      }
      $message = 'Sorry, %ip has been greylisted by <a href="%ipurl">http:BL</a>.<br>You may try whitelisting on <a href="%whitelisturl">%whitelisturl</a>.%honeypot';
