A permanent cookieis stored on the client's browser, as part of the response from a Web site's server. It is sent by the browser when the client makes subsequent requests to the same site, even after the browser has been shut down.
A temporary cookieis only valid for the current browser session. Similar to a SSL Session- based ID, the temporary cookie expires when you shut down the browser. Based on RFC 2109, any cookie without an expiration date is a temporary cookie.
