public static interface VirtualHostDiscoveryServiceGrpc.AsyncService
 Virtual Host Discovery Service (VHDS) is used to dynamically update the list of virtual hosts for
 a given RouteConfiguration. If VHDS is configured a virtual host list update will be triggered
 during the processing of an HTTP request if a route for the request cannot be resolved. The
 :ref:`resource_names_subscribe <envoy_api_field_DeltaDiscoveryRequest.resource_names_subscribe>`
 field contains a list of virtual host names or aliases to track. The contents of an alias would
 be the contents of a *host* or *authority* header used to make an http request. An xDS server
 will match an alias to a virtual host based on the content of :ref:`domains'
 <envoy_api_field_route.VirtualHost.domains>` field. The *resource_names_unsubscribe* field
 contains a list of virtual host names that have been :ref:`unsubscribed
 <xds_protocol_unsubscribe>` from the routing table associated with the RouteConfiguration.
