.B \-b, \-\-backend=(<HOST>,<PORT>|unix:<PATH>)[;<PATTERN>[:...]]
|
2015-03-14 10:52:50 +01:00
|
|
|
Set backend host and port. The multiple backend
|
|
|
|
addresses are accepted by repeating this option. UNIX
|
|
|
|
domain socket can be specified by prefixing path name
|
2015-07-11 05:45:23 +02:00
|
|
|
with "unix:" (e.g., unix:/var/run/backend.sock).
|
|
|
|
.sp
|
|
|
|
Optionally, if <PATTERN>s are given, the backend address
|
2015-07-12 16:26:45 +02:00
|
|
|
is only used if request matches the pattern. If \fI\%\-s\fP or
|
|
|
|
\fI\%\-p\fP is used, <PATTERN>s are ignored. The pattern
|
|
|
|
matching is closely designed to ServeMux in net/http
|
|
|
|
package of Go programming language. <PATTERN> consists
|
2015-07-14 17:01:04 +02:00
|
|
|
of path, host + path or just host. The path must start
|
|
|
|
with "\fI/\fP". If it ends with "\fI/\fP", it matches all request
|
|
|
|
path in its subtree. To deal with the request to the
|
|
|
|
directory without trailing slash, the path which ends
|
|
|
|
with "\fI/\fP" also matches the request path which only lacks
|
|
|
|
trailing \(aq\fI/\fP\(aq (e.g., path "\fI/foo/\fP" matches request path
|
|
|
|
"\fI/foo\fP"). If it does not end with "\fI/\fP", it performs exact
|
|
|
|
match against the request path. If host is given, it
|
|
|
|
performs exact match against the request host. If host
|
|
|
|
alone is given, "\fI/\fP" is appended to it, so that it
|
|
|
|
matches all request paths under the host (e.g.,
|
|
|
|
specifying "nghttp2.org" equals to "nghttp2.org/").
|
|
|
|
.sp
|
|
|
|
Patterns with host take precedence over patterns with
|
|
|
|
just path. Then, longer patterns take precedence over
|
2015-07-12 16:26:45 +02:00
|
|
|
shorter ones, breaking a tie by the order of the
|
|
|
|
appearance in the configuration.
|
2015-07-11 05:45:23 +02:00
|
|
|
.sp
|
|
|
|
If <PATTERN> is omitted, "\fI/\fP" is used as pattern, which
|
2015-07-14 17:01:04 +02:00
|
|
|
matches all request paths (catch\-all pattern). The
|
|
|
|
catch\-all backend must be given.
|
2015-07-11 05:45:23 +02:00
|
|
|
.sp
|
|
|
|
When doing a match, nghttpx made some normalization to
|
|
|
|
pattern, request host and path. For host part, they are
|
|
|
|
converted to lower case. For path part, percent\-encoded
|
|
|
|
unreserved characters defined in RFC 3986 are decoded,
|
|
|
|
and any dot\-segments (".." and ".") are resolved and
|
|
|
|
removed.
|
|
|
|
.sp
|
|
|
|
For example, \fI\%\-b\fP\(aq127.0.0.1,8080;nghttp2.org/httpbin/\(aq
|
|
|
|
matches the request host "nghttp2.org" and the request
|
|
|
|
path "\fI/httpbin/get\fP", but does not match the request host
|
|
|
|
"nghttp2.org" and the request path "\fI/index.html\fP".
|
|
|
|
.sp
|
|
|
|
The multiple <PATTERN>s can be specified, delimiting
|
|
|
|
them by ":". Specifying
|
|
|
|
\fI\%\-b\fP\(aq127.0.0.1,8080;nghttp2.org:www.nghttp2.org\(aq has the
|
|
|
|
same effect to specify \fI\%\-b\fP\(aq127.0.0.1,8080;nghttp2.org\(aq
|
2015-07-14 17:01:04 +02:00
|
|
|
and \fI\%\-b\fP\(aq127.0.0.1,8080;www.nghttp2.org\(aq.
|
2015-07-11 05:45:23 +02:00
|
|
|
.sp
|
|
|
|
The backend addresses sharing same <PATTERN> are grouped
|
2015-07-14 17:01:04 +02:00
|
|
|
together forming load balancing group.
|
|
|
|
.sp
|
|
|
|
Since ";" and ":" are used as delimiter, <PATTERN> must
|
|
|
|
not contain these characters. Since ";" has special
|
|
|
|
meaning in shell, the option value must be quoted.

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

Path to file that contains 48 bytes random data to

|
|
|
|
can be used repeatedly to specify multiple ticket
|
|

key is used to encrypt TLS session tickets. Other keys

are accepted but server will issue new session ticket
|

with first key. This allows session key rotation.
|

Please note that key rotation does not occur

automatically. User should rearrange files or change

options values and restart nghttpx gracefully. If

while opening or reading a file, key is generated

nghttpx supports HTTP/2 server push in default mode. nghttpx looks

and pushes those URIs to the frontend client. Here is a sample Link

.INDENT 0.0

.IP 1. 3
|

URI\-reference must not contain authority. If it exists, it is not

|
|
pushed. \fB/fonts/font.woff\fP and \fBcss/theme.css\fP are eligible to
|
|
|

be pushed. \fBhttps://example.org/fonts/font.woff\fP and

\fB//example.org/css/theme.css\fP are not.

The associated stream must have method "GET" or "POST". The

.SH UNIX DOMAIN SOCKET
|
|
|
|
.sp
|
|
|
|
nghttpx supports UNIX domain socket with a filename for both frontend
|
|
|
|
and backend connections.
|
|
|
|
.sp
|
|
|
|
Please note that current nghttpx implementation does not delete a
|
|
|
|
socket with a filename. And on start up, if nghttpx detects that the
|
|
|
|
specified socket already exists in the file system, nghttpx first
|
|
|
|
deletes it. However, if SIGUSR2 is used to execute new binary and
|
|
|
|
both old and new configurations use same filename, new binary does not
|
|
|
|
delete the socket and continues to use it.

OCSP query is done using external Python script
|
|
|
|
\fBfetch\-ocsp\-response\fP, which has been originally developed in Perl
|
|
|
|
as part of h2o project (\fI\%https://github.com/h2o/h2o\fP), and was
|
|
|
|
translated into Python.

|
|
|
|
The script file is usually installed under
|
|
|
|
\fB$(prefix)/share/nghttp2/\fP directory. The actual path to script can
|
|
|
|
be customized using \fI\%\-\-fetch\-ocsp\-response\-file\fP option.
