|
|
[\fI\,OPTIONS\/\fR]... [\fI\,<PRIVATE_KEY> <CERT>\/\fR]
|
|
.SH DESCRIPTION
|
|
A reverse proxy for HTTP/2, HTTP/1 and SPDY.
|
|
.TP
|
|
<PRIVATE_KEY>
|
|
Set path to server's private key. Required
|
|
unless \fB\-p\fR, \fB\-\-client\fR or \fB\-\-frontend\-no\-tls\fR are
|
|
given.
|
|
.TP
|
|
<CERT>
|
|
Set path to server's certificate. Required
|
|
unless \fB\-p\fR, \fB\-\-client\fR or \fB\-\-frontend\-no\-tls\fR are
|
|
given.
|
|
.SH OPTIONS
|
|
.IP
|
|
The options are categorized into several groups.
|
|
.SS "Connections:"
|
|
.TP
|
|
\fB\-b\fR, \fB\-\-backend=\fR<HOST,PORT>
|
|
Set backend host and port.
|
|
Default: '127.0.0.1,80'
|
|
.TP
|
|
\fB\-f\fR, \fB\-\-frontend=\fR<HOST,PORT>
|
|
Set frontend host and port. If <HOST> is '*', it
|
|
assumes all addresses including both IPv4 and
|
|
IPv6.
|
|
Default: '*,3000'
|
|
.TP
|
|
\fB\-\-backlog=\fR<NUM>
|
|
Set listen backlog size. If \fB\-1\fR is given,
|
|
libevent will choose suitable value.
|
|
Default: \fB\-1\fR
|
|
.TP
|
|
\fB\-\-backend\-ipv4\fR
|
|
Resolve backend hostname to IPv4 address only.
|
|
.TP
|
|
\fB\-\-backend\-ipv6\fR
|
|
Resolve backend hostname to IPv6 address only.
|
|
.TP
|
|
\fB\-\-backend\-http\-proxy\-uri=\fR<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
|
|
\fB\-\-backend\-read\-timeout\fR and
|
|
\fB\-\-backend\-write\-timeout\fR options.

.TP
|
|
\fB\-\-worker\-write\-burst=\fR<SIZE>
|
|
Set maximum write burst size on frontend

|
.TP
|
|
(default mode)
|
|
Accept HTTP/2, SPDY and HTTP/1.1 over SSL/TLS.
|
|
If \fB\-\-frontend\-no\-tls\fR is used, accept HTTP/2 and
|
|
HTTP/1.1. The incoming HTTP/1.1 connection can
|
|
be upgraded to HTTP/2 through HTTP Upgrade. The

|
Like default mode, but enable secure proxy mode.
|
|
.TP
|
|
\fB\-\-http2\-bridge\fR
|
|
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
|
|
\fB\-\-backend\-http\-proxy\-uri\fR option if you are behind
|

the proxy and want to connect to the outside
|
|
HTTP/2 proxy.
|
|

|
|
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 \fB\-p\fR option
|
|
instead.
|
|
.TP
|
|
\fB\-p\fR, \fB\-\-client\-proxy\fR
|
|
Like \fB\-\-client\fR option, but it also requires the

request path from frontend must be an absolute
|
|
URI, suitable for use as a forward proxy.
|
|
.SS "Logging:"
|
|
.TP
|
|
\fB\-L\fR, \fB\-\-log\-level=\fR<LEVEL>

Don't append to Via header field. If Via header
|
|
field is received, it is left unaltered.
|
|
.TP
|
|
\fB\-\-no\-location\-rewrite\fR
|
|
Don't rewrite location header field on
|
|
\fB\-\-http2\-bridge\fR, \fB\-\-client\fR and default mode. For

|
this option.
|
|
.TP
|
|
\fB\-\-altsvc=\fR<PROTOID,PORT[,HOST,[ORIGIN]]>
|
|
Specify protocol ID, port, host and origin of
|
|
alternative service. <HOST> and <ORIGIN> are
|
|
optional. They are advertised in alt\-svc header

alternative services. Example: \fB\-\-altsvc\fR=\fI\,h2\/\fR,443
|
|
.TP
|
|
\fB\-\-add\-response\-header=\fR<HEADER>
|
|
Specify additional header field to add to

.TP
|
|
\fB\-\-frontend\-http2\-dump\-request\-header=\fR<PATH>
