I was wondered when I try to check my squid proxy server by using http://cache.jp.apan.net/proxy-checker/ .. it said :

Caution!!, The proxy is accessible to anyone. However it does not generate any variable which indicates the original client IP address. The software of the proxy must be changed. Otherwise, an access restriction must be established.

Proxy Variables
HTTP_X_FOWARDED_FOR:
HTTP_FORWARDED:
HTTP_VIA:

.. my question is how to close it? and idea and or suggestion would be greatly appreciated and many thanks in advance

Regards
Winan
