title: .NET MVC API - dots (period) in get request
body: <p>I'm trying to setup Facebook Notification API.
  I have an APi Controller with RealtimeUpdate() - Get, will be used just for verification of endpoint.</p>
  
  <p>As is written in Fb Docs:</p>
  
  <blockquote>
    <p>Firstly, Facebook servers will make a single HTTP GET to your callback
    URL when you try to add or modify a subscription. A query string will
    be appended to your callback URL with the following parameters:</p>
    
    <ul>
    <li>hub.mode - The string "subscribe" is passed in this parameter</li>
    <li>hub.challenge - A random string </li>
    <li>hub.verify_token - The verify_token value you specified when you created the subscription</li>
    </ul>
  </blockquote>
  
  <p>From here I have a problem - I have no idea how to handle this dots in query params names. I google a lot, and did not find the solution.</p>
  
  <p>Can somebody please say to me how to get data from this hub.* values?</p>
  
  <p>Thank you!</p>
