Add support for reverse proxy

maxmeyerrequested to merge
(removed):feature/add-support-for-reverse-proxy into master

This MR make gitlab-pages daemon parse the X-Forwarded-Host header and use it in a reverse proxy setup. According to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-Host X-Forwarded-Host is the de-facto standard header to pass the requested hostname in a reverse-proxy-setup.

  • Build daemon

    make

  • Run daemon

    ./gitlab-pages -listen-proxy 0.0.0.0:8081 -log-verbose

  • Test daemon

    curl -H "X-Forwarded-Host: group.gitlab-example.com" localhost:8081/index.html
# => OK

I also verified the functionality by copying the binary into the standard docker container of Gitlab CE.
