Can the cookie expire when some time has passed or the browser is closed?

Question

I know that I can set the expiration date for the cookie, but can I make the cookie expire after a while or when the browser is closed?

Answer 1

If you set an expiration date, this will expire that date, regardless of whether the browser is open or closed.

Only cookies that are not saved will be valid after the browser is closed.

See cookie expiration rules on wikipedia.
