The previous code isn't bullet proof at all, if I know there are some private parts, what
forbids me to add a X_FORWARDED_FOR with a local address even though I'm not on the LAN, or
even worse, the field could be present for anyone using a proxy and using a LAN even if it's
not the trusted one, for exemple if the user at the other end is behind a NATed router.
Be very cautious because is way too easy to be fooled with such a method
