Note Submitter: admin at SexDev dot com ---- The problem with empty HTTP_X_FORWARDED_FOR is because of anonymous proxy servers: Anonymous - HTTP Proxy server does not send HTTP_X_FORWARDED_FOR variable to host, this improves privacy since your IP address cannot be logged. High anonymity - HTTP Servers of this type don’t send HTTP_X_FORWARDED_FOR, HTTP_VIA and HTTP_PROXY_CONNECTION variables. Host doesn’t even know you are using proxy server an of course it doesn’t know your IP address.
