A server http://www.webopedia.com/TERM/p/proxy_server.html that sits between a client application as a Web browser and a real server. It intercepts all requests to the real server to see if it can meet the same application. If not so, sends the request to the real server. Proxy servers have two main purposes: Improving Performance: Proxy servers can improve performance for user groups. This is because it saves the results of all requests for a certain amount of time. Consider the case where both user X and user Y access the World Wide Web through a proxy server. First user X requests a particular Web page, we'll call Page 1. Some time later, the requests user and the same page. Instead of transmitting the request to the Web server resides on a page, which can be a long operation, the proxy server simply returns the Page 1 that it was brought to the user X. Since the proxy server is often on the same network as the user, this is a much faster operation. Real proxy servers support hundreds or thousands of users. The major online services like America Online, MSN and Yahoo, for example, employ a variety of proxy servers. Filter Applications: Proxy servers can also be used to filter requests. For example, a company might use a proxy server to prevent its employees have access to a specific set of web sites
