A cookie is a file containing an identifier (a string of letters and numbers) that a web server sends to a web browser and that the browser stores. The browser sends the identifier back to the server each time the browser requests a page from the server.
Cookies may be either “persistent” cookies or “session” cookies; a persistent cookie will be stored by a web 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 when the user closes the web browser.
Cookies generally do not contain any information that personally identifies a user, but personal data we store about you may be linked to the information stored in and obtained from cookies.
Most browsers automatically collect cookies, but you do not have to accept a cookie, and you can in fact modify your browser so that it will not accept cookies. For more information about cookies including how to set your internet browser to reject cookies please go to www.allaboutcookies.org.
