What are cookies?

A cookie is a small text file that a website stores on your computer or mobile device when you visit the site.

  • First party cookies are cookies set by the website you’re visiting. Only that website can read them. In addition, a website might potentially use external services, which also set their own cookies, known as third-party cookies.
  • Persistent cookies are cookies saved on your computer and that are not deleted automatically when you quit your browser, unlike a session cookie, which is deleted when you quit your browser.

The first time you visit the ESRF website, you will be prompted to accept or refuse cookies. After a period of six months you will be asked again.

The purpose is to enable the site to remember your preferences (such as user name, language, etc.) for a certain period of time.

That way, you don’t have to re-enter them when browsing around the site during the same visit.

Cookies can also be used to establish anonymised statistics about the browsing experience on our sites.
