title: Redirect to another action with id
body: <p>In my ASP MVC controller I want to redirect to another controller and action with an <em>id</em>:</p>
  
  <pre><code>int thisEvent = 20;
  return Redirect("event/details/?id=" + thisEvent);
  </code></pre>
  
  <p>It should redirect to <strong>/event/details/?id=200</strong> or <strong>/event/details/20</strong> For some reason it is not working. </p>
  
  <p>I get this error:</p>
  
  <blockquote>
    <p>Redirect URI cannot contain newline characters</p>
  </blockquote>
