.B \-b, \-\-backend=<HOST,PORT>
.B \-b, \-\-backend=(<HOST>,<PORT>|unix:<PATH>)[;<PATTERN>[:...]]
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
with "unix:" (e.g., unix:/var/run/backend.sock)
with "unix:" (e.g., unix:/var/run/backend.sock).
.sp
Optionally, if <PATTERN>s are given, the backend address
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
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
shorter ones, breaking a tie by the order of the
appearance in the configuration.
.sp
If <PATTERN> is omitted, "\fI/\fP" is used as pattern, which
matches all request paths (catch\-all pattern). The
catch\-all backend must be given.
.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
and \fI\%\-b\fP\(aq127.0.0.1,8080;www.nghttp2.org\(aq.
.sp
The backend addresses sharing same <PATTERN> are grouped
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.

The options are categorized into several groups.
Connections:
-b, --backend=<HOST,PORT>
-b, --backend=(<HOST>,<PORT>|unix:<PATH>)[;<PATTERN>[:...]]
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
with "unix:" (e.g., unix:/var/run/backend.sock)
with "unix:" (e.g., unix:/var/run/backend.sock).
Optionally, if <PATTERN>s are given, the backend address
is only used if request matches the pattern. If -s or
-p is used, <PATTERN>s are ignored. The pattern
matching is closely designed to ServeMux in net/http
package of Go programming language. <PATTERN> consists
of path, host + path or just host. The path must start
with "/". If it ends with "/", it matches all request
path in its subtree. To deal with the request to the
directory without trailing slash, the path which ends
with "/" also matches the request path which only lacks
trailing '/' (e.g., path "/foo/" matches request path
"/foo"). If it does not end with "/", 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, "/" is appended to it, so that it
matches all request paths under the host (e.g.,
specifying "nghttp2.org" equals to "nghttp2.org/").
Patterns with host take precedence over patterns with
just path. Then, longer patterns take precedence over
shorter ones, breaking a tie by the order of the
appearance in the configuration.
If <PATTERN> is omitted, "/" is used as pattern, which
matches all request paths (catch-all pattern). The
catch-all backend must be given.
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.
For example, -b'127.0.0.1,8080;nghttp2.org/httpbin/'
matches the request host "nghttp2.org" and the request
path "/httpbin/get", but does not match the request host
"nghttp2.org" and the request path "/index.html".
The multiple <PATTERN>s can be specified, delimiting
them by ":". Specifying
-b'127.0.0.1,8080;nghttp2.org:www.nghttp2.org' has the
same effect to specify -b'127.0.0.1,8080;nghttp2.org'
and -b'127.0.0.1,8080;www.nghttp2.org'.
The backend addresses sharing same <PATTERN> are grouped
together forming load balancing group.
Since ";" and ":" are used as delimiter, <PATTERN> must
not contain these characters. Since ";" has special
meaning in shell, the option value must be quoted.
