( i don't really get how you can detect the user correctly if the proxy is configured to not make this information public, only monitoring in and outgoing connections would make this possible imho) |

The values of these headers are not hard coded into any server operating system - they can be changed by the server administrator. In the case of a legitamite proxy system (such as AOL, or your company internet server) these variables might be configured properly. (There are no rules or regulations regarding this!) However, in the case of an anonymous proxy service, these headers will probably not contain anything. Why would you use an anonymous proxy if it broadcast where you orginally came from? | The values of these headers are not hard coded into any server operating system - they can be changed by the server administrator.

Since there is no way your server can determine such use, the only way to detect an anonymous proxy is by trying to actually use it. http://www.countrycheck.com will attempt to connect to the server in the same way a user would. This connection attempt, and a few other tests, are done in real time. CountryCheck maintains a large database of proxy servers and this list is updated on a constant basis. | Since there is no way your server can determine such use, the only way to detect an anonymous proxy is by trying to actually use it. http://www.countrycheck.com will attempt to connect to the server in the same way a user would.

These lists change daily. Usually an anonymous proxy is created by a virus or trojan, and then plugged as soon as the administrator detects it - mostly due to increased traffic. Because of this, many proxy lists float around on the internet, but they are outdated almost as fast as they are used. | These lists change daily.
