title: Going to the router URL directly is not working
body: <p>I'm using react-router, and everything is working fine except when I go to the URL directly. For example, if I clicked on a Link in the app that goes to "/quizreview?quizId=nAUl3DmFlX" it works with no problem. But if I entered the URL "<a href="http://localhost:3000/quizreview?quizId=nAUl3DmFlX" rel="nofollow noreferrer">http://localhost:3000/quizreview?quizId=nAUl3DmFlX</a>" it says:</p>
  
  <p>Cannot GET /quizreview?quizId=nAUl3DmFlX</p>
  
  <p>Here is my router code:</p>
  
  <pre><code>ReactDOM.render((
  &lt;Router history={browserHistory}&gt;
      &lt;Route path="/" component={App}&gt;
          &lt;IndexRoute component={UserQuiz} onEnter={loginRequired}/&gt;
          &lt;Route path="/login" component={Login}/&gt;
          &lt;Route path="/quiz/:id" component={Quiz}/&gt;
          &lt;Route path="/quizreview" component={PostQuiz}/&gt;
          &lt;Route path="/quizquestions/:quizId" component={QuestionForm}/&gt;
          &lt;Route path="/questionreview/:questionId" component={QuestionReview}/&gt;
          &lt;Route path="/noquestions" component={NoQuestionsDialog}/&gt;
      &lt;/Route&gt;
  &lt;/Router&gt;
  ), document.getElementById('app'));
  </code></pre>
  
  <p>Am I doing anything wrong here? I followed the React-Router tutorial and it's working fine and I believe I followed the same instructions but with this problem occuring.</p>
