Ah, right. Me, too, actually, which is why I still have the 4.0.6 manual on
my PC!

No, I wouldn't expect them to as the manual explicitly says they won't.

Yes. I'd expect that too -- the 4.0.6 manual is again quite clear that you
can only get variables into your session with session_register().
What it's not so clear about is whether
session_register('foo');
$HTTP_SESSION_VARS['foo'] = 'bar';
will set the session variable foo to 'bar' under all circumstances -- it
im-plies that it should when register_globals is off, but is very ambiguous
about exactly what happens when register_globals is on.
Thanks for the heads-up on this topic -- I'm just about to start writing
some code which will make heavy use of sessions, and initially it will have
to work for version 4.0.6 (until my site admin decides to upgrade), so I
guess I've got some heavy testing in prospect on my test server to work out
exactly what all the combinations do -- I need to write stuff that will work
regardless of register_globals, and will continue to work unchanged when the
eventual upgrade to 4.3.x comes along.
Cheers!
Mike
