title: Silently authentication from webview
body: <p>Here's what I want to have figured out : I'm using a webview to access a feature of a site that requires authentication. Therefore whenever that particular link is loaded the  login page is displayed . Is is possible to somehow authenticate silently so that the particular feature is displayed directly ?  Perhaps by using the "webView.setHttpAuthUsernamePassword" (which does not seem to work for me, or I don't do it right) or by making some POST or GET before I load the page , or other possibility ? </p>
  
  <p>On logging in the server is simply supposed to send me a cookie.</p>
