Proxies are store-and-forward caches. When you configure your web browser to use a proxy, it never connects to the URL. Instead, it always connects to the proxy server, and asks it to get the URL for you. Proxies can be used as a sort of firewall, because it isolates you from connecting to the Internet. When you use a proxy server, your computer will send a request to the proxy server, then the proxy server will send it to the destination (for example a website), the destination will answer the request the proxy has sent and finally the proxy will return the data to you computer. For example when you visit http://supertrickz.blogspot.com/ via proxy.
