title: Can OWIN middleware use the http session?
body: <p>I had a little bit of code that I was duplicating for ASP.NET and SignalR and I decided to rewrite it as OWIN middleware to remove this duplication.</p>
  
  <p>Once I was running it I noticed that <code>HttpContext.Current.Session</code> was null, and I didn't see any session object on the <code>IOwinContext</code> that my middleware has.  </p>
  
  <p>Is it possible to access the http session from OWIN?  </p>
