/**
 * 
 * .. attention::
 *   Internally, Envoy always uses the HTTP/2 ``:authority`` header to represent the HTTP/1 ``Host``
 *   header. Thus, if attempting to match on ``Host``, match on ``:authority`` instead.
 * .. attention::
 *   To route on HTTP method, use the special HTTP/2 ``:method`` header. This works for both
 *   HTTP/1 and HTTP/2 as Envoy normalizes headers. E.g.,
 *   .. code-block:: json
 *     {
 *       "name": ":method",
 *       "string_match": {
 *         "exact": "POST"
 *       }
 *     }
 * .. attention::
 *   In the absence of any header match specifier, match will default to :ref:`present_match
 *   <envoy_v3_api_field_config.route.v3.HeaderMatcher.present_match>`. i.e, a request that has the :ref:`name
 *   <envoy_v3_api_field_config.route.v3.HeaderMatcher.name>` header will match, regardless of the header's
 *   value.
 *  [#next-major-version: HeaderMatcher should be refactored to use StringMatcher.]
 * [#next-free-field: 15]

  /**
   * 
   * .. attention::
   *   Internally, Envoy always uses the HTTP/2 ``:authority`` header to represent the HTTP/1 ``Host``
   *   header. Thus, if attempting to match on ``Host``, match on ``:authority`` instead.
   * .. attention::
   *   To route on HTTP method, use the special HTTP/2 ``:method`` header. This works for both
   *   HTTP/1 and HTTP/2 as Envoy normalizes headers. E.g.,
   *   .. code-block:: json
   *     {
   *       "name": ":method",
   *       "string_match": {
   *         "exact": "POST"
   *       }
   *     }
   * .. attention::
   *   In the absence of any header match specifier, match will default to :ref:`present_match
   *   <envoy_v3_api_field_config.route.v3.HeaderMatcher.present_match>`. i.e, a request that has the :ref:`name
   *   <envoy_v3_api_field_config.route.v3.HeaderMatcher.name>` header will match, regardless of the header's
   *   value.
   *  [#next-major-version: HeaderMatcher should be refactored to use StringMatcher.]
   * [#next-free-field: 15]
   * 
   *
