in December 1991.

  It was around 24 years ago in Amsterdam. To be precise the 2nd of December, 1991. At the same time that Mikhail Gorbachev was thinking about resigning as President of the Union of Soviet Socialist Republics, a group of enthusiasts met to discuss about the first Norm about odour concentration measurement. Today, 33 countries of Europe are using this norm to measure odour concentration. But that was not easy a few years back.

   To start with this history we should go back to 1984.

What are cookies?

   A cookie is a text file stored in a user’s web browser on any device they use to access a website that holds information regarding the user’s visit, such as preferences. When the user returns, the browser provides the cookie with the stored information to the site.

What cookies are used for?

   Cookies are used for adjusting a website’s content to fit a user’s preferences and optimize the website. They store useful information that improve the user’s experience of a website. They are most commonly used for:

  •     Recognizing the type of device a user is browsing with and any preferences applied to optimize the website specifically for the device.

When a website requires that you verify your age or location once every visit before allowing you to view content and without requiring additional personal details, that is a session cookie at work.
