docs: Allows access from ``domain``, which may be either a full
          domain name, or a wildcard (e.g., ``*.example.com``, or simply
          ``*``). Due to security concerns, it is strongly recommended
          that you use explicit domains rather than wildcards.
  
          For socket policy files, pass a list of ports or port ranges
          as the keyword argument ``to_ports``. As with ``domain``, a
          wildcard value -- ``*`` -- will allow all ports.
  
          To disable Flash's requirement of security matching (e.g.,
          retrieving a policy via HTTPS will require that SWFs also be
          retrieved via HTTPS), pass ``secure=False``. Due to security
          concerns, it is strongly recommended that you not disable
          this.
