The browser will send the old cookie and as the name is probably the same as the
the old session it will get used again, or at least I think that is what is
happening :)
This should not be a problem as the data associated with the old session is

If that is the case, then the setcookie() call to destroy the clien't cookie probably isn't neccessary.

If you close the browser and start a fresh one you will get a new session id.
