Use `x-forwarded-for` as `Host`

[KaKi87]

Hello,

I'm running the app using Docker through Apache : it displays the former's IP in Host despite the real IP being present in x-forwarded-for.

Thanks

Host would be incorrect, as Host is the hostname (and port) that you ask the webserver to serve.
The correct header would be X-Forwarded-Host, if you want the hostname forwarded.

X-Forwarded-For contains the client IP
