you can tag a session with an EXPIREREF, and before the session
record is deleted, we can call a function that will pass the EXPIREREF
as the first parameter, and the session key as the second parameter.
To do this, define a notification function, say NotifyFn:
function NotifyFn($expireref, $sesskey)
{
}
Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.
