title: App with MVC Virtual application shared AuthCookie
body: <p>I have a 3.5 ASP.Net WebForm parent application.  The parent uses forms authentication.<br>
   I have a MVC child virtual application, I would like to make it so the user logs in to the parent application, user then navigates to the virtual application by pressing a link on the parent.
   However every time I do this it goes to the login screen for the virtual application.</p>
  
  <p>Is there a web setting I should double check in Parent?   Or Child?</p>
  
  <p>Is there an IIS setting that I should check?</p>
  
  <p>Should I be using a virtual directory instead of virtual application?  I want the child to be able to access the Session[] from the parent.  I would like the child app to use the same authCookie as the parent app.    </p>
