The most common types of cookies are explained below for your information.
While you are using a website, a session cookie containing a session identifier is temporarily stored in your computer's memory, e.g. so that you do not need to log on again every time you change webpages. Session cookies are deleted when you log off or cease to be valid as soon as your session automatically expires.
A permanent or protocol cookie stores a file on your computer for the duration defined by the file's expiration date. These cookies enable websites to remember your information and settings the next time you visit them. This speeds up your access and makes it more convenient, for instance because you do not need to adjust your language setting for our portal every time. The cookie is automatically deleted once its expiration date is reached when you visit the website that generated the cookie.
