|
|
Set backend host and port. For HTTP/1 backend, multiple
|
|
backend addresses are accepted by repeating this option.
|
|
HTTP/2 backend does not support multiple backend
|
|
addresses and the first occurrence of this option is

used.

.B \-\-backend\-http\-proxy\-uri=<URI>
|
|
Specify proxy URI in the form

\fI\%http:/\fP/[<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 \fI\%\-\-backend\-read\-timeout\fP and
|
|
\fI\%\-\-backend\-write\-timeout\fP options.

Please note that key rotation does not occur

automatically. User should rearrange files or change
