title: UI-router redirect to different url?
body: <p>This might not even be possible, but I'm going to try anyway. In my website I have a couple of states defined with <code>ui-router</code>. One of these states should link to another domain. Is this possible?</p>
  
  <pre><code>$stateProvider
    .state('index', {
      url: "/index",
      templateUrl: "views/home.html",
      controller: "MainController",
      ncyBreadcrumb: {
          label: 'Home'
      }
    })
    .state('about', {
      url: "/about",
      templateUrl: "views/about.html",
      controller: "AboutController",
      ncyBreadcrumb: {
          label: 'About',
          parent: 'index'
      }
    })
    .state('Us', {
      url: "/us",
      parent: "about",
      views : {
        '@': {
          templateUrl: 'views/us.html',
        },
      }
    })
    .when('contact', 'http://www.example.com')
  </code></pre>
