Determines originating IP address. REMOTE_ADDR is the standard but will be wrong if the user is behind a proxy. Proxies will set HTTP_CLIENT_IP and/or HTTP_X_FORWARDED_FOR, so we prioritize those. HTTP_X_FORWARDED_FOR may be a comma-delimited list in the case of multiple chained proxies. The last address which is not a known proxy will be the originating IP.
