A proxy allows you to surf the web with the help of an intermediary server that can boost performance and provide a level of security for you. Most of the time, if you need to change or fix your proxy server settings, it is the result of your network administrator request. Popular browsers allow you to change your proxy settings with a few clicks of your mouse.
