Many users are using proxy server to hide their digital footprint. In other words, if a proxy server is used, any request to the web site first comes to the proxy, and then it transmits this request further to its destination. Companies use clients IP address and browser cookie to track user activities, and the Internet is not a trusted medium to share information. Proxy server is a computer that acts as an intermediary for data exchange between the user and Internet resources. Free proxies are usually public proxies or errors of system administrators who do not bother to change the default settings or set a password.
