If the session is expired you will get an empty session - i.e.
the session would not be loaded.

What do you mean?

If the user had lost the session due to timeout it would have to login
again. 


There are also several models of session expiration:

See, NEVER store valuable information information 

in the session. This is not what the session is for.

Session may expire, be deleted, the user may loose the
cookie. So sessions is not good for this purpose.
