What Is a Persistent Cookie?

A persistent cookie is a cookie which is stored in a cookie file permanently on the
browser's computer. By default, cookies are created as temporary cookies which stored
only in the browser's memory. When the browser is closed, temporary cookies will be
erased. You should decide when to use temporary cookies and when to use persistent
cookies based on their differences:
· Temporary cookies can not be used for tracking long-term information.
· Persistent cookies can be used for tracking long-term information.
· Temporary cookies are safer because no programs other than the browser can
access them.
· Persistent cookies are less secure because users can open cookie files see the
cookie values.
