I'm setting up Nginx as a caching HTTP server for Steam and Origin game downloads on my LAN.
Is it necessary for Nginx to send the
X-Forwarded-For headers to the servers, if:
- The IP addresses will always be RFC1918 addresses (192.168, 172.16, 10.)
- No state needs to be tracked by the upstream content servers
If it is unlikely to cause problems, I'd like to disable sending these headers to save a tiny amount of bandwidth.
