Is it possible to extend the lifetime of the CraftSessionId cookie? I would like to extend the lifetime of the CraftSessionId cookie. Is this possible and if so, where can I change the value?

Thank you for your time.
Craft's CraftSessionId cookie is simply the PHP Session cookie renamed and by default it's terminated when the browser is closed.

Craft currently doesn't expose any way to alter that behavior, but you can always make a feature request!
