title: saving and retrieving values from session state in asp.net
body: <p>I am reviewing some web code and I am not exactly sure how ASP.net session state works. Any helps would be gratefully appreciated.</p>
  
  <p>If a User object is saved to the session state during login, and User.FirstName and User.LastName is set. If other web pages retrieve the user object from the session and set the FirstName to something else is that persisted on other web pages? Or, do you need to re-add the user object back to the session once it has been modified? Thanks</p>
