To make this site work properly, we sometimes place very small data files called cookies on your device. Most websites these days do this too.

What are cookies?

A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.

Almost all modern websites use cookies. They have many applications, such as: tracking users as they navigate around a website to improve their browsing experience; remembering user preferences and shopping cart contents; auto-logins for visitors coming back to a site; and website security.

What are the different types of cookies?

A cookie can be classified by its lifespan and the domain to which it belongs. By lifespan, a cookie is either a:

  • session cookie which is erased when the user closes the browser, or
  • persistent cookie which remains on the user's computer/device for a pre-defined period of time.

As for the domain to which it belongs, there are either:

  • first-party cookies which are set by the web server of the visited page and share the same domain, or
  • third-party cookies stored by a different domain to the visited page's domain. This can happen when the webpage references a file, such as JavaScript, located outside its domain.
