public final class HttpProtocolOptions extends com.google.protobuf.GeneratedMessageV3 implements HttpProtocolOptionsOrBuilder
 HttpProtocolOptions specifies Http upstream protocol options. This object
 is used in
 :ref:`typed_extension_protocol_options<envoy_v3_api_field_config.cluster.v3.Cluster.typed_extension_protocol_options>`,
 keyed by the name ``envoy.extensions.upstreams.http.v3.HttpProtocolOptions``.

 This controls what protocol(s) should be used for upstream and how said protocol(s) are configured.

 This replaces the prior pattern of explicit protocol configuration directly
 in the cluster. So a configuration like this, explicitly configuring the use of HTTP/2 upstream:

 .. code::

   clusters:
     - name: some_service
       connect_timeout: 5s
       upstream_http_protocol_options:
         auto_sni: true
       common_http_protocol_options:
         idle_timeout: 1s
       http2_protocol_options:
         max_concurrent_streams: 100
        .... [further cluster config]

 Would now look like this:

 .. code::

   clusters:
     - name: some_service
       connect_timeout: 5s
       typed_extension_protocol_options:
         envoy.extensions.upstreams.http.v3.HttpProtocolOptions:
           "@type": type.googleapis.com/envoy.extensions.upstreams.http.v3.HttpProtocolOptions
           upstream_http_protocol_options:
             auto_sni: true
           common_http_protocol_options:
             idle_timeout: 1s
           explicit_http_config:
             http2_protocol_options:
               max_concurrent_streams: 100
        .... [further cluster config]

    • hasRetryPolicy

      public boolean hasRetryPolicy()
       Specifies the retry policy for requests routed to this cluster. When configured,
 cluster-level retry policy overrides route-level retry policy. When not configured,
 route-level retry policy (if any) will be used.

   Cluster-level retry policy will override route-level retry policy entirely. Policies are
   not merged.
