What are Cookies?

Cookies are information packets sent by web servers to web browsers, and stored by the web browsers. The information is then sent back to the server each time the browser requests a page from the server. This enables a web server to identify and track web browsers. There are two main kinds of cookies: session cookies and persistent cookies. Session cookies are deleted from your computer when you close your browser, whereas persistent cookies remain stored on your computer until deleted, or until they reach their expiry date.


Types of Cookies

Cookies can be classified as either ‘essential’ or ‘non-essential’.

Essential cookies: these are cookies that are either:

  • used solely to carry out or facilitate the transmission of communications over a network; or
  • strictly necessary to provide an online service (e.g. our website or a service on our website) which you have requested.

Non-essential cookies: these are any cookies that do not fall within the definition of essential cookies, such as cookies used to analyse your behaviour on a website (‘analytical’ cookies) or cookies used to display advertisements to you (‘advertising’ cookies).


Session and Persistent Cookies

Cookies can be classified as either ‘session’ or ‘persistent’, depending on how long they last after they are placed on your browser.

Session cookies: session cookies last for as long as you keep your browser open. They expire when you close your browser.

Persistent cookies: persistent cookies expire at a fixed point in time or if you manually delete them from your browser, whichever occurs first.


Cookie Classifications

Cookies can be classified as ‘first party’ or ‘third party’.

First party cookies: these are cookies placed on your device by our website domain.

Third party cookies: these are cookies placed on your device by third party website domains.
