This implementation of IWebProxy supports HTTP proxies. Use the one-argument form of the constructor to specify the URI of the proxy server. The second argument, BypassOnLocal, if set to true, bypasses the proxy server for local (intranet) addresses. Other forms of the constructor allow you to specify an array that lists servers for which you should bypass the proxy (this list can contain regular expression strings containing URI patterns to match). You can also supply network credentials to authenticate your application to the proxy server.

See GlobalProxySelection or the WebRequest.Proxy property for details on configuring a proxy.
