title: SessionID is same but session data are not same
body: <p>I created two different very simple apps (ASP .NET) and host on the local iis. 
  Both apps are open in same browser in two tabs. In first application (AppA) I store some data in Session (Session["name"] = "john") and in second application (AppB) I read this value. When I explore cookies (with FireCookie) I saw that SessionIDs for both applications are same. Also, In both apps SessionID is printed and are the same. When I try get this value in AppB from session (with correct key), session is empty, but session id is still same. In AppA session data are still alive.</p>
  
  <p>Why session data are different when both apps ask web server (with same session id) to return data?</p>
