title: React Router redirect IndexRoute to proper path
body: <p>I'm trying to configure React Router so that when accessing http://url/manage/roomId it goes directly to http://url/manage/roomId/sessions (loading RoomSessions component). These are tabs components' routes and I want to load the first tab's content (which it does) by default with the proper URL (which it does not).</p>
  <p>It works fine except for the redirection</p>
  <pre><code>&lt;Route
      path=&quot;manage/:roomId&quot;
      component={RoomsManagerManageRoom}
      onEnter={requireAuth}
  &gt;
      &lt;IndexRoute component={RoomSessions} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;sessions&quot; component={RoomSessions} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;meetings&quot; component={RoomMeetings} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;files&quot; component={RoomFiles} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;recordings&quot; component={RoomRecordings} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;sections&quot; component={RoomSections} onEnter={requireAuth} /&gt;
      &lt;Route path=&quot;hosts&quot; component={RoomHosts} onEnter={requireAuth} /&gt;
  &lt;/Route&gt;
  </code></pre>
  <p>What am I missing?</p>
