title: SignalR breaks on every other page refresh until I do a ctrl+F5
body: <p>SignalR is working great except on every other page load, I get:</p>
  
  <p><img src="https://i.stack.imgur.com/KzkK8.png" alt="errors"></p>
  
  <p>The error in the start and abort are</p>
  
  <p><strong>Unrecognized user identity.  The user identity cannot change during an active SignalR connection.</strong></p>
  
  <p>At this point, though, if I do a ctrl+f5, it works great.</p>
  
  <p>I'm on IIS 7.5 which means it's not using web sockets, if that matters.</p>
