Using VOSA cookies

A cookie is a small piece of text that is sent to your browser from a Web site you visit. It helps the site remember information about your visit, such as. your preferred language and other settings. This makes your next visit easier and the site more usable. Cookies plays an important role. Without them it would be much more frustrating to use it.

We use cookies for a variety of purposes. We use them for example to remember your preferences for SafeSearch, so the ads you see, is more appropriate for you to count how many visitors we receive on a page to help you to subscribe to our services and to protect your data.

Do you have any questions about the use of cookies on our site, please contact us by email




A cookie is a simple text file that is stored on a user’s computer or mobile device when visiting certain websites.

The use of cookies on EUROPA is allowed under certain conditions.


What is a cookie?

A cookie is a text file no bigger than 4k that a website asks your browser to store on your computer or mobile device. This allows the website to “remember” your actions or preferences over a period of time.

Most browsers support cookies however users can set their browsers to decline them and can also delete them whenever they like.

What are they used for?

Websites mainly use cookies:

  • to identify users
  • to remember the user’s custom preferences
  • to help complete a task without having to re-enter information when browsing from one page to another or when visiting the site again sometime later

Cookies can also be used for online behavioral target advertising and show adverts relevant to something that the user searched for in the past.

How are they used?

The web server supplying the webpage can store a cookie on the user’s computer or mobile device. An external web server that manages files included or referenced in the webpage is also able to store cookies. All these cookies are called http header cookies. Another way of storing cookies is through JavaScript code contained or referenced in that page.

Each time the user requests a new page, the web server can receive the values of the cookies it previously set and return the page with content relating to these values. Similarly, JavaScript code is able to read a cookie belonging to its domain and perform an action accordingly.

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
  • 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.

What does EU legislation say?

It is important that EUROPA follows the Commission’s guidelines on privacy and data protection and informs users that cookies are not being used in an intrusive way.

The ePrivacy directive and more specifically Article 5(3) requires prior informed consent for storage or access to information stored on a user’s terminal equipment. In other words, you must ask users if they agree to most cookies and similar technologies (e.g. web beacons, Flash cookies, etc.) before the site starts to use them.

For consent to be valid, it must be informed, specific, freely given and must constitute a real indication of the individual’s wishes.

However, some cookies are exempt from this requirement and so you don’t have to ask for consent if the cookie:

  • is used for the sole purpose of carrying out the transmission of a communication and,
  • is strictly necessary in order for the provider of an information society service explicitly required by the user to provide the service.

Cookies clearly exempt from consent according to the EU advisory body on data protection- WP29pdf(698 kB)opinion:

  • user input cookies (session-id) such as first-party cookies to keep track of the user’s input when filling online forms, shopping carts, etc., for the duration of a session or persistent cookies limited to a few hours in some cases
  • authentication cookies, to identify the user once he has logged in, for the duration of a session
  • user-centric security cookies, used to detect authentication abuses, for a limited persistent duration
  • multimedia content player cookies, used to store technical data to play back video or audio content, for the duration of a session
  • load balancing cookies, for the duration of session
  • user interface customization cookies such as language or font preferences, for the duration of a session (or slightly longer)
  • third-party social plug-in content sharing cookies, for logged-in members of a social network.


The use of cookies on EUROPA is allowed under certain conditions.

  1. Reflect on whether the use of cookies is really necessary for a given functionality and if there is no other non-intrusive alternative.
  2. If a cookie is essential, asses how intrusive your cookie is: what data does each cookie hold, is it linked to other information held about the user? Is its lifespan appropriate to its purpose? What type of cookie is it? Is it a first or a third-party setting the cookie? Who controls the data?
  3. Evaluate for each cookie if informed consent is required or not:
    • first-party session cookies do not require informed consent
    • first-party persistent cookies require informed consent. Use only when strictly necessary. The expiry period must not exceed one year
    • all third-party session and persistent cookies require informed consent. These cookies should not be used on EUROPA sites as the data collected may be transferred beyond the EU’s legal jurisdiction.
  4. Gain consent from the users, if required, before storing cookies by implementing the Cookie Consent Kit in all the pages of any website using cookies that require informed consent.
  5. Inform users about the use of cookies in plain, jargon-free language in a dedicated “cookie notice” page linked from the service toolbar of the standard templates. This page should explain:
    • the reason why they are being used, (e.g. to remember users’ actions, to identify the user, to collect traffic information)
    • if they are essential for the website or a given functionality to work or if they aim to enhance the performance of the website
    • the types of cookies used (e.g. session or permanent, first or third-party)
    • who controls/accesses the cookie-related information (website or third party)
    • that the cookie will not be used for any purpose other than the one stated
    • how consent can be withdrawn.

    standard template to create your own cookie notice pagezip(236 kB) is available. If a site does not use any cookies, the dedicated “cookie notice” page should use the template and just mention this. If your site uses the same cookies as the Commission homepage, you can link to the top level cookie notice. 

Cookie Consent Kit

The cookie consent solution is a JavaScript based kit that, after some site-specific configuration, will automatically add a header banner on the page. This header banner will disappear once the user has accepted or refused the cookies used on the site.

This solution provides the following functionalities:

  • JavaScript to automatically display the header banner in 24 languages
  • a wizard to declare your cookies and the link to your cookies notice page
  • a JavaScript API with methods and functions that help to prevent prior storage of cookies
  • a corporate consent cookie to remember the choice of the user across websites
  • a template for the cookie notice page.

This is a central service; you have to call the main JavaScript file on your website and add a one site-specific configuration file listing the cookies you are using. You will also have to add a short HTML parameter to every element in your site that sets a cookie.

Read the full documentation to implement the Cookie Consent Kit.

  1. The cookie header banner displayed on all pages of a site using cookies that require informed consent.
  2. A link to the specific cookie notice page is also available.
