public final class FilterConfig extends com.google.protobuf.GeneratedMessageV3 implements FilterConfigOrBuilder
 Configuration for the filter state based dynamic forward proxy filter. See the
 :ref:`architecture overview <arch_overview_http_dynamic_forward_proxy>` for
 more information. Note this filter must be used in conjunction to another filter that
 sets the 'envoy.upstream.dynamic_host' and the 'envoy.upstream.dynamic_port' filter
 state keys for the required upstream UDP session.
