1. Session Cookies
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.
2. Permanent Cookies (Protocol Cookies)
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.
3. Third Party Cookies
Third party cookies stem from a provider who is not the operator of the website. They can be used, e.g., to collect information for purposes of advertising, user-defined content, and web statistics.
4. Flash Cookies
Data elements that are stored on your computer by a website are referred to as flash cookies if Adobe Flash is used to operate them. Flash cookies have no time limit.
