Cookies overview 

What are cookies

Cookies are small files stored by websites on your computer. They make your online experience easier by saving browsing information.

Sites use cookies to:

  • keep you signed in

Advertisers use tracking cookies to follow you around the web, recording your interests and habits.

Turn cookies off when necessary

You can disable cookies in any web browser. You can turn them off from the settings area of the browser you are using – it does not depend on the type of computer.

If you use more than one type of browser, then you need to check cookies on each of them.

Type of cookies

There are several types of cookies. Here below there is a few list of them:

  • First-party cookies are created by the site you visit.
  • Third-party cookies are created by other sites. These sites own some of the content, like ads or images, that you see on the webpage you visit
  • Session cookies are used only when a person is actively navigating a website; once you leave the site, the session cookie disappears.
  • Tracking cookies may be used to create long-term records of multiple visits to the same site.
  • Authentication cookies track whether a user is logged in, and if so, under what name.

To know more about cookies, read this the Wikipedia page “HTTP cookie”.
