--backend-http-proxy-uri=<URI>
Specify proxy URI in the form
http://[<USER>:<PASS>@]<PROXY>:<PORT>. If a
proxy requires authentication, specify <USER> and
<PASS>. Note that they must be properly
percent-encoded. This proxy is used when the
backend connection is HTTP/2. First, make a
CONNECT request to the proxy and it connects to
the backend on behalf of nghttpx. This forms
tunnel. After that, nghttpx performs SSL/TLS
handshake with the downstream through the tunnel.
The timeouts when connecting and making CONNECT
request can be specified by
--backend-read-timeout and

Mode:
(default mode) Accept HTTP/2, SPDY and HTTP/1.1 over SSL/TLS.
If --frontend-no-tls is used, accept HTTP/2 and

be upgraded to HTTP/2 through HTTP Upgrade. The
protocol to the backend is HTTP/1.1.
-s, --http2-proxy Like default mode, but enable secure proxy mode.
--http2-bridge Like default mode, but communicate with the
backend in HTTP/2 over SSL/TLS. Thus the
incoming all connections are converted to HTTP/2
connection and relayed to the backend. See
--backend-http-proxy-uri option if you are behind
the proxy and want to connect to the outside
HTTP/2 proxy.
--client Accept HTTP/2 and HTTP/1.1 without SSL/TLS. The
incoming HTTP/1.1 connection can be upgraded to
HTTP/2 connection through HTTP Upgrade. The
protocol to the backend is HTTP/2. To use
nghttpx as a forward proxy, use -p option
instead.
