title: SignalR 2 connection not being persisted
body: <p>I've set up a sample SignalR hub, ChatHub, added list of connections. When it runs OnConnected I see it being add to the List. However when I open that page in another browser (expecting the list to have 2 connections now I see 0 connections in my list). Is ChatHub instantiated per request?</p>
  
  <pre><code>    List&lt;string&gt; connections = new List&lt;string&gt;();
      public override Task OnConnected()
      {
          connections.Add(Context.ConnectionId);
          return base.OnConnected();
      }
  </code></pre>
