A proxy server acts as an intermediary for requests between a client and a server. In simple, the traffic flows through the proxy server on its way to the address you requested and back.
A proxy server for automation scripts with Selenium could be helpful for:
If you are in a corporate environment, and a browser fails to connect to a URL, this is most likely because the environment needs a proxy to be accessed.
Selenium WebDriver provides a way to proxy settings
