title: Using res.location with res.render
body: <p>I have the user submit a file using POST to <code>/upload</code>, then I want the browser to render <code>index.mustache</code> and tell the browser that the location is <code>/</code>. I attempted to do this with the following code (in multer's <code>onFileUploadComplete</code>):</p>
  
  <pre><code>res.location('/');
  res.render('index', {options: 'whatever'});
  </code></pre>
  
  <p>It renders <code>index</code>, but the browser displays the location as <code>/upload</code>, not <code>/</code> as I desire. What am I doing wrong?</p>
