Описание тега http-proxy
An HTTP Proxy is a server that receives requests from your web browser and then makes the request to the Internet on your behalf. It then returns the results to your browser.
A proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers.
A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.
Today, most proxies are web proxies, facilitating access to content on the World Wide Web.
