IIRC, the cookie RFC (RFC2109, http://www.rfc-editor.org/rfc/rfc2109.txt)
states that a cookie without an expiration will be discarded when the user
closes the browser.  At a cursory look, I can't find the chapter and
verse, but I'm pretty sure it's in there.  Netscape's cookie page
(http://home.netscape.com/newsref/std/cookie_spec.html) *does* spell this
out explicitly.

Enjoy.
