The DNS-notation of i.e. * domains (with trailing dot) is implicitly supported by the protocols and service daemons in use, but can lead to potential issues if not taken explicit care of:

  • Some software does not support the notation
  • Cookies set for either notation may not be shared

Thus we should introduce a globally ensured rule in our HTTP-daemon configuration, redirecting any request where Host: $HOSTNAME. to $HOSTNAME without the trailing dot.
