My experience with HTTP authentication is that once you try to get fancy
it's easier to use your own authentication method instead. What I might
do in your case is use the #aboutToViewPage: method on Session to make
sure you're logged in before showing any pages. Something like
(user isNil or: [self isTimedOut]) ifTrue:
[aPage isAuthenticationPage ifFalse:
[user := aPage callPage: (MyAuthPage new)]]
super aboutToViewPage: aPage.
Does this make sense? I should probably just include such a session,
since I imagine it's generally useful.

IATransaction isn't an alternative, it is used as part of session - for a
little more about transactions, see the end of tutorial 2. Basically,
they group page views together that can expire en-masse.
