About cookies

A persistent cookie consists of a text file sent by a web server to a web browser, which will be stored by the browser and will remain valid until its set expiry date (unless deleted by the user before the expiry date). A session cookie, on the other hand, will expire at the end of the user session, when the web browser is closed.
