  // matches only a single label. You cannot have a wildcard label by itself (e.g. Host == "*").

  // 1. If Host is precise, the request matches this rule if the http host header is equal to Host.
  // 2. If Host is a wildcard, then the request matches this rule if the http host header
  // is to equal to the suffix (removing the first label) of the wildcard rule.
