A cookie is a file containing information packet that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server. Cookies can be used by web servers to identify and track web browsers.
There are two main types of cookies: “persistent” cookies or “session” 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.
You can find out more about cookies via the resource www.aboutcookies.org.
