transient cookie (session cookie)
On the Web, a transient cookie, sometimes called a session cookie, is a small file that
contains information about a user that disappears when the user's browser
is closed. Unlike a persistent cookie, a transient cookie is not stored on your hard drive but is
only stored in temporary memory
that is erased when the browser is closed.
A transient cookie is created by simply not setting a date in the Set-Cookie option when an
application creates the cookie.
(For a persistent cookie, an expiration date is set and the cookie is stored on the user's hard
drive until the expiration date or until the user deletes it.)
Transient cookies are often used to enable a site to be able to track the pages that a user has
visited during a visit so that information can be customized for the user in some way. Some sites
use Secure Sockets Layer (SSL) to encrypt the information contained in a cookie.
