HTTP Proxy

Sometimes it’s handy to use a proxy like nginx to forward requests to an internal server. If you do this then you need to set these headers to make Group-Office operate proprly:

• X-Forwarded-Proto : http or https. This is the protocol the proxy server uses.
• X-Forwarded-Host : The hostname of the proxy server.
