title: calling the Caller method in SignalR hub outside the hub context
body: <p>I have a question in my mind about the Caller method of SignalR. In the hub method we can call a client side function like this.</p>
  
  <pre><code>Clients.Caller.addContosoChatMessageToPage(name, message);
  </code></pre>
  
  <p>but when i use to call it from outside the hub context it is not found or not implemented?? like this..</p>
  
  <pre><code> var context = GlobalHost.ConnectionManager.GetHubContext&lt;MyHub&gt;();
   context.Clients.Caller.reportProgress(recordCount,totalCount);
  </code></pre>
  
  <p>Can someone enlighten me in this part or is there other way to implement it..
  by now i use to implement this</p>
  
  <pre><code> var context = GlobalHost.ConnectionManager.GetHubContext&lt;MyHub&gt;();
   context.Clients.User(CurrentUser.Usernm).reportProgress(recordCount,totalCount);
  </code></pre>
  
  <p>but now we are not claim based authentication so it will be a problem if the same usernm are logged..</p>
