title: How to redirect to an external URL from angular2 route without using component?
body: <p>I  would like to create an external redirect, but to make all routes consistent I think it would be nice to do everything(including external redirects) under Router States configuration.</p>
  
  <p>so:</p>
  
  <pre><code>const appRoutes: Routes = [
    {path: '', component: HomeComponent},
    {path: 'first', component: FirstComponent},
    {path: 'second', component: SecondComponent},
    {path: 'external-link', /*would like to have redirect here*/}      
  ];
  </code></pre>
  
  <p><strong>UPD</strong>: and <strong>I don't want to use empty component for this case</strong> like <strong>@koningdavid</strong> suggested. This solution looks really weird for me. It should be something really easy to implement for such case, without virtual components.</p>
