title: How can I get fragment value from server side?
body: <p>My url is:</p>
  
  <pre><code>http://localhost:4567/Test/Callback#state=test&amp;access_token=....
  </code></pre>
  
  <p>But when calling <code>Request.Url.ToString();</code> it just outputs</p>
  
  <pre><code>http://localhost:4567/Test/Callback
  </code></pre>
  
  <p>How can I get the full url send to the server?</p>
