Our own experience is that the PHP method to define custom session
handlers is broken -
'write' doesn't work. At least in earlier versions (4.0.0, 4.0.1, for
sure). We've no real
need to go back, because we're written our own which server our purpose
just fine. Even if
you're working on just one server, it's often handy to be able to do an
SQL call to 'view' some
of the raw session data.
