WHAT KINDS OF COOKIES ARE THERE?

  • Session cookies — These are temporary cookies that are stored in the browser’s memory until the browser is closed. These commonly used for online shopping carts and other short term storage purposes.
  • Persistent cookies — These cookies track you until their issuer dictated expiration date. These cookies track your activity across websites and report the data back either when you revisit the site or view a site that contains a resource (like a display ad) issued by the original cookie issuers. Persistent cookies are users when you click the “Remember Me” option on a website.
  • First-party cookies — These are cookies issued by the website you are currently visiting. They are used to customize the experience for the user.
  • Third-party cookies — These are cookies that are added by a domain that isn’t the one you’re visiting. The most common kind of third-party cookie tracks users after they click an ad and associates them with the referred domain

  • Security concerns include session hijacking and cross-site request forgery
