Configuration for the Original Destination cluster.

• bool use_http_header = 1

  When true, an HTTP header can be used to override the original dst address. The default header is :ref:`x-envoy-original-dst-host <config_http_conn_man_headers_x-envoy-original-dst-host>`. .. attention:: This header isn't sanitized by default, so enabling this feature allows HTTP clients to route traffic to arbitrary hosts and/or ports, which may have serious security consequences. .. note:: If the header appears multiple times only the first value is used.

• string http_header_name = 2

  The http header to override destination address if :ref:`use_http_header <envoy_v3_api_field_extensions.clusters.original_dst.v3.OriginalDstCluster.use_http_header>` is set to true. If the value is empty, :ref:`x-envoy-original-dst-host <config_http_conn_man_headers_x-envoy-original-dst-host>` will be used.

• optional google.protobuf.UInt32Value upstream_port_override = 3

  The port to override for the original dst address. This port will take precedence over filter state and header override ports.

• optional type.metadata.v3.MetadataKey metadata_key = 4

  The dynamic metadata key to override destination address. First the request metadata is considered, then the connection one.
