A proxy server sits between your device and the internet.
Therefore, when using a proxy, you will not have direct access to the Internet, but your web requests will first be routed through the proxy before being sent to the web server. Proxy protocols are the rules that are applied during data exchange between a device and a proxy server. HTTP proxy is one of the common proxy protocol types.
