title: Angular redirect on startup or writing wrong URL
body: <p>i wanted to ask if its possible i could redirect every URL after "localhost:4200" to "localhost:4200/Welcome" if sth else is typed in the url. But afterwards it should be possible to reach other URL like "localhost:4200/Files", just not about passing the URL in the browser. Here my routes:</p>
  
  <pre><code>const routes: Routes = [
  { path: '', redirectTo: '/Welcome', pathMatch: 'full' },
  { path: 'Welcome', component: LoaderComponent},
  { path: 'Files', component: RowOfDataComponent },
  { path: 'Files/newFiles/:lid', component: DataArrowComponent },
  { path: '**', redirectTo: '/Welcome' }
  
  ];
  </code></pre>
  
  <p>So everytime someone trys to write sth else in the URL than "localhost:4200/Welcome" he shall be redirect to "localhost:4200/Welcome".</p>
  
  <p>I would really appreciate your help, already thanks for reading through.</p>
