title: Apache HttpClient 4.1 - Proxy Authentication
body: <p>I've been trying to configure the user and password for proxy authentication from the configured properties while using Apaches HttpComponent's httpclient, but with no success. All examples I have found refer to methods and classes that are no longer available, such as <code>HttpState</code> and <code>setProxyCredentials</code>. </p>
  
  <p>So, can anyone give me an example of how to configure the proxy credentials?</p>
