Select backend based on request host and path by extending -b option
-b option syntax is now <HOST>,<PORT>[;<PATTERN>[:...]]. The optional <PATTERN>s specify the request host and path it is used for. The <PATTERN> can contain path, host + path or host. The matching rule is closely designed to ServeMux in Go programming language.

|

The options are categorized into several groups.
|
||||
|
||||
Connections:
|
||||
-b, --backend=<HOST,PORT>
|
||||
-b, --backend=<HOST>,<PORT>[;<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, -p,
|
||||
--client or --http2-bridge 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 host. The
|
||||
path must starts with "/". If it ends with "/", it
|
||||
matches to the request path whose prefix is the path.
|
||||
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
|
||||
paths under the host (e.g., specifying "nghttp2.org"
|
||||
equals to "nghttp2.org/"). 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 paths (catch-all pattern). 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.
|
||||
Default: )" << DEFAULT_DOWNSTREAM_HOST << ","
|
||||
<< DEFAULT_DOWNSTREAM_PORT << R"(
|
||||
-f, --frontend=<HOST,PORT>
|
||||
-f, --frontend=<HOST>,<PORT>
|
||||
Set frontend host and port. If <HOST> is '*', it
|
||||
assumes all addresses including both IPv4 and IPv6.
