placeholders

caution

log format append 的 value 只支持 global 的 placeholder
- 因为日志是在 HTTP 请求上下文之外处理的
- 不支持 per-request placeholders

directive	for
`handle [<matcgher>]`
`handle_path <path_matcher>`	handle+uri_strip_prefix
`handle_errors [<status_codes...>]`
`route [<matcgher>]`	类似 handle, 但只分组不互斥, 不重排

@mutable `{method}.startsWith("P")`
expression {method}.startsWith("P")

example.com {
  gzip
  reverse_proxy / 127.0.0.1:9000 {
    transport fastcgi
	}
}

example.com {
	root * /var/www

rewrite * {path}?{query}&host={host}

重写 header 到 path

abc-dev.domain.co -> abc/def/{uri}

@parseHost header_regexp parsedHost Host ^([a-z0-9]+)-([a-z0-9]+)\.domain\.co$
root @parseHost /opt/serve/{re.parsedHost.2}/stages/{re.parsedHost.1}

abc.builds.wener.me -> abc/{uri}
- http.request.host.labels 从 0 开始

*.builds.wener.me {
  root * /opt/serve/builds/{http.request.host.labels.3}
  try_files {path} /index.html
  file_server
}
