Web Server Internal IP Address/Internal Network Name Disclosure Vulnerability

[Mon Yang]

Hi,

I did QualysGuard scan and it says "Web Server Internal IP
Address/Internal Network Name Disclosure Vulnerability".  It suggest
for Apache, I need to:


For Apache Web Server:
Modify the Apache configuration file as follows:
- Set "ServerName" to a proper FQDN.
or
- Use module mod_rewrite to modify the 3xx error message returned by the server.

So what I need to do in nginx to fix this issue?  Thank you.
