openshift - X-Forwarded-Host header 在已设置时不应被 HaProxy 覆盖

Question

有人能告诉我如何在 openshift 3.11 中配置自定义 ha 代理路由器(haproxy-config.template)，避免 X-Forwarded-Host、X-Forwarded-Port 和 X-Forwarded-Proto header 不应该被覆盖HaProxy 已经设置好。不设置header时，按照HTTP标准设置。

我试过了 https://access.redhat.com/solutions/3986281但它不工作。

谢谢，桑托斯

下面的代码对我有用:

旧配置:

   http-request set-header X-Forwarded-Host %[req.hdr(host)]
   http-request set-header X-Forwarded-Port %[dst_port]
   http-request set-header X-Forwarded-Proto http if !{ ssl_fc }
   http-request set-header X-Forwarded-Proto https if { ssl_fc }

更改为新的:

   acl h_xfh_exists req.hdr(X-Forwarded-Host) -m found
   http-request set-header X-Forwarded-Host %[req.hdr(host)] unless h_xfh_exists
   acl h_xfport_exists req.hdr(X-Forwarded-Port) -m found
   http-request set-header X-Forwarded-Port %[dst_port] unless h_xfport_exists
   acl h_xfproto_exists req.hdr(X-Forwarded-Proto) -m found
   http-request set-header X-Forwarded-Proto http if !{ ssl_fc } !h_xfproto_exists
   http-request set-header X-Forwarded-Proto https if { ssl_fc } !h_xfproto_exists
