I think Dave answered it well. I think the Users Online thing is
another example. If you have, on average, 200 users on your site, and
you are only showing it for "ego reasons", then why not let it be a

The cost of locking may outweigh the value of an individual data point.

It's the ability to replicate the sessions across a cluster that is the
crucial difference between J2EE session and non-J2EE sessions.

Just a note that it's also easy to make normal CF sessions end on browser
close by copying the cfid and cftoken cookie into a session-only cookie.
It's about 4 lines of code.

I think you should be a bit careful on wording here. Doing structClear
on a session will NOT timeout the session. It just removes the data in
it. So for example, onSessionEnd will not fire.

As you say, they a
J2EE sessions also automatically end (for the user) when the browser
is closed instead of persisting, as J2EE sessions are tracked with
session (i.e. in-memory) cookies rather than persistent ones.

Rick:
even if there weren't any differences from a coding standpoint, the
fact that you can choose between the two still suggests that they are
different (at least different enough that the choice is there).
J2EE sessions end on browser close. traditional cf sessions do not.
you can time out a
Correct, the J2EE session variables are required to replicate them across a
cluster. However, whether you need to lock them or not has nothing to do
with the type of session variable you choose, but on the potential for race
conditions in the code itself.

Well, the interviewer was actually asking if I used j2ee session
variables, to which I would've quickly answered "no"
But as far as coldfusion is concerned, There's only one type of
session variables. Those are variables placed in the session scope.
Whether or not they are J2EE session variable
Personally, it's a terrible question. I'd say something like:

I had an interviewer ask me the following question.
"What types of session variables do you use?"
Before reading any of the responses to this thread, I'd like to know
how you would answer that question.
Do you mean ColdFusion in built scopes, or custom ones?
