// [#protodoc-title: Upstream HTTP/1.1 Proxy]
// [#extension: envoy.transport_sockets.http_11_proxy]
// HTTP/1.1 proxy transport socket establishes an upstream connection to a proxy address
// instead of the target host's address. This behavior is triggered when the transport
// socket is configured and proxy information is provided.
//
// Behavior when proxying:
// =======================
// When an upstream connection is established, instead of connecting directly to the endpoint
// address, the client will connect to the specified proxy address, send an HTTP/1.1 ``CONNECT`` request
// indicating the endpoint address, and process the response. If the response has HTTP status 200,
// the connection will be passed down to the underlying transport socket.
//
// Configuring proxy information:
// ==============================
// Set ``typed_filter_metadata`` in :ref:`LbEndpoint.Metadata <envoy_v3_api_field_config.endpoint.v3.lbendpoint.metadata>` or :ref:`LocalityLbEndpoints.Metadata <envoy_v3_api_field_config.endpoint.v3.LocalityLbEndpoints.metadata>`.
// using the key ``envoy.http11_proxy_transport_socket.proxy_address`` and the
// proxy address in ``config::core::v3::Address`` format.
//
