+
+  Supports `#{inspect(@methods)}` HTTP methods, and only allows `#{inspect(@valid_resp_codes)}` status codes.
+
+  Responses are chunked to the client while downloading from the upstream.
+
+  Some request / responses headers are preserved:
+
+  * request: `#{inspect(@keep_req_headers)}`
+  * response: `#{inspect(@keep_resp_headers)}`
+
+  If no caching headers (`#{inspect(@resp_cache_headers)}`) are returned by upstream, `cache-control` will be
+  set to `#{inspect(@default_cache_control_header)}`.
+
+  Options:
+
+  * `redirect_on_failure` (default `false`). Redirects the client to the real remote URL if there's any HTTP
+  errors. Any error during body processing will not be redirected as the response is chunked. This may expose
+  remote URL, clients IPs, ….
+
+  * `max_body_length` (default `#{inspect(@max_body_length)}`): limits the content length to be approximately the
+  specified length. It is validated with the `content-length` header and also verified when proxying.
+
+  * `max_read_duration` (default `#{inspect(@max_read_duration)}` ms): the total time the connection is allowed to
+  read from the remote upstream.
+
+  * `inline_content_types`:
+    * `true` will not alter `content-disposition` (up to the upstream),
+    * `false` will add `content-disposition: attachment` to any request,
+    * a list of whitelisted content types
+
+    * `keep_user_agent` will forward the client's user-agent to the upstream. This may be useful if the upstream is
+    doing content transformation (encoding, …) depending on the request.
+
+  * `req_headers`, `resp_headers` additional headers.
+
