Proxy servers are used throughout the Internet. They act as middlemen between a user and a server on the Internet or on another type of network. A proxy judge is a type of program used on them.
Uses of Proxy Servers
Proxy servers act as a filter between you and the Internet.
Private computer networks, such as the types used in many workplaces, can monitor how people use the Internet and possibly filter out certain kinds of traffic, such as websites employees don't need to use for work.
Proxy servers may also protect users from malware (malicious programs, such as viruses) by filtering out certain files, so that a user's computer or private network never receives them.
Proxy servers often give users anonymous access to the Internet, by blocking the IP (Internet) address someone is using.
Proxy servers are available in two basic types: anonymous and transparent (not anonymous). Someone who wants an anonymous server may have to test a proxy to determine which type it is.
Proxy judges are programs that test proxy servers. They're often installed on other servers to test certain proxies. Test data is sent to the proxy server, and the proxy judge determines which type the tested server is, according to how the data is sent back.
Personal Proxy Judges
People who have access to their own web servers may use their own proxy judges. Some proxy judge scripts include ProxyJudge, AZ Environment Variables and JEnv by G-Lock Software.
Sometimes, publicly available servers that run proxy judges are slow, due to a lot of people using them. People who use their own proxy judge servers usually can test proxy servers in less time.
