title: When is the earliest I can access SESSION in the ASP.NET MVC page lifecycle?
body: <p>My question is essentially the same as question <a href="https://stackoverflow.com/questions/765054/whens-the-earliest-i-can-access-some-session-data-in-global-asax">765054</a> on StackOverflow.  I'm only asking it again because the accepted answer is incorrect (you can not access the session object in Application_BeginRequest).  </p>
  
  <p>Our use case is that we want to store the authenticated user's user object in the session.  So in subsequent requests, we can correctly set the IPrincipal and IIdentity based on the user object in session.  </p>
