title: Apache HttpClient (4.1 and newer): how to do basic authentication?
body: <p>How do I add basic authentication for the default client of the httpClient library? I have seen examples where they use <code>client.getCredentialProvider()</code>, however I think all of this methods are for library version 4.0.1 or 3.x. Is there a new example of how to do this?  Thanks a lot.</p>
