Answer 1

do you use reverse proxy like apache proxy? http://httpd.apache.org/docs/2.2/mod/mod_proxy.html

When acting in a reverse-proxy mode (using the ProxyPass directive, for example), mod_proxy_http adds several request headers in order to pass information to the origin server. These headers are:

X-Forwarded-For
The IP address of the client.
X-Forwarded-Host
The original host requested by the client in the Host HTTP request header.
X-Forwarded-Server
The hostname of the proxy server.
