    public static final class RouteAction.RequestMirrorPolicy.Builder
extends com.google.protobuf.GeneratedMessageV3.Builder<RouteAction.RequestMirrorPolicy.Builder>
implements RouteAction.RequestMirrorPolicyOrBuilder
     The router is capable of shadowing traffic from one cluster to another. The current
 implementation is "fire and forget," meaning Envoy will not wait for the shadow cluster to
 respond before returning the response from the primary cluster. All normal statistics are
 collected for the shadow cluster making this feature useful for testing.
 During shadowing, the host/authority header is altered such that ``-shadow`` is appended. This is
 useful for logging. For example, ``cluster1`` becomes ``cluster1-shadow``.
 .. note::
   Shadowing will not be triggered if the primary cluster does not exist.

      • getClusterHeader

        public String getClusterHeader()
         Only one of ``cluster`` and ``cluster_header`` can be specified.
 Envoy will determine the cluster to route to by reading the value of the
 HTTP header named by cluster_header from the request headers. Only the first value in header is used,
 and no shadow request will happen if the value is not found in headers. Envoy will not wait for
 the shadow cluster to respond before returning the response from the primary cluster.
 .. 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.
 .. note::
   If the header appears multiple times only the first value is used.
        string cluster_header = 5 [(.validate.rules) = { ... }
        Specified by:
        getClusterHeader in interface RouteAction.RequestMirrorPolicyOrBuilder
        Returns:
        The clusterHeader.
