title: Get connectionId outside of Hub, SignalR
body: <p>How do I get the clients connectionId/clientId outside of the Hub?.. I have managed to do the following:</p>
  
  <pre><code>var context = GlobalHost.ConnectionManager.GetHubContext&lt;MyHub&gt;();
  </code></pre>
  
  <p>But in that context-object there is no such thing as a <code>clientId</code>.</p>
