// [#protodoc-title: Upstream HTTP/1.1 Proxy]
// [#extension: envoy.transport_sockets.http_11_proxy]

// Configuration for HTTP/1.1 proxy transport sockets.
// This is intended for use in Envoy Mobile, though may eventually be extended
// for upstream Envoy use.
// If this transport socket is configured, and an intermediate filter adds the
// stream info necessary for proxying to the stream info (as the test filter
// does :repo:`here <test/integration/filters/header_to_proxy_filter.cc>`) then
//
// * Upstream connections will be directed to the specified proxy address rather
//   than the host's address
// * Upstream TLS connections will have a raw HTTP/1.1 CONNECT header prefaced
//   to the payload, and 200 response stripped (if less than 200 bytes)
// * Plaintext HTTP/1.1 connections will be sent with a fully qualified URL.
//
// This transport socket is not compatible with HTTP/3, plaintext HTTP/2, or raw TCP.
