I run nikto on a server, let's say www.example.com and it says the following:
OSVDB-630: The web server may reveal its internal or real IP in the Location header via a request to / over HTTP/1.0. The value is "A.B.C.D".
I have nginx as a reverse proxy with ip "A.B.C.D" and behind a few web servers. Is really risky revealing the private address?
If so, how can I prevent that http client gets the nginx private IP address?
