我刚刚添加并提交了对 mod_proxy_core 的头部重写支持。

$HTTP["url"] =~ "^/proxyme(/|$)" {
  proxy-core.balancer = "round-robin"
  proxy-core.protocol = "http"
  proxy-core.backends = ( "en.wikipedia.org" )
  proxy-core.rewrite-response = (
    "Location" => ( "^http://en.wikipedia.org/(.*)" => "http://127.0.0.1:1025/proxyme/$1" ),
  )
  proxy-core.rewrite-request = (
    "_uri" => ( "^/proxyme/?(.*)" => "/$1" ),
    "Host" => ( ".*" => "en.wikipedia.org" ),
 )
}

wget 现在运行正常，并通过代理按预期跟踪重定向

$ wget http://127.0.0.1:1025/proxyme/
--15:18:20--  http://127.0.0.1:1025/proxyme/
           => `index.html.1'
Connecting to 127.0.0.1:1025... connected.

这以一种非常通用的方式实现了“ProxyPassReverse”：https://httpd.apache.ac.cn/docs/1.3/mod/mod_proxy.html#proxypassreverse。“ProxyPass”：https://httpd.apache.ac.cn/docs/1.3/mod/mod_proxy.html#proxypass 与请求中的 Host: 重写相同。一切都通过 URL 条件控制，并将代理限制在 /proxyme/ URL。
