How works a proxy

Internet Proxy servrs are deployed in most environments for security, performance, and usage tracking purposes. When your application makes a request to a resource on the Internet, the request is often routed through a proxy. The proxy then makes the request on your behalf and forwards the response back to you. This means that your application needs to know what proxy server to use when requesting a resource on the Internet. You can or use an explicit proxy server name or may take advantage of the automatic proxy detection capabilities.
