A cookie is a small text file that is stored on your computer. Cookies may contain text and numbers, including e.g. dates. Cookies are not programs and do not contain viruses or similar malicious codes. Cookies serve to allow a website to store specific information with the user, so that the website can later recognize the user or load that information. It can for example. include login information, information about previous visits, and what parts of the website you have visited. Cookies can only be loaded by the address (website) from which they are stored.
Ordinary cookies stored from the website are typically stored from the address you see in the browser's address bar. However, a website may also contain fragments and information that are retrieved from addresses other than the one displayed in the browser's address bar. It can for example. be banner advertising or analysis tools, but also plain content. In this way, cookies from other addresses can also be stored through the website you actually visit - so-called third-party cookies. Some cookies (so-called session cookies) are only stored in a browser session and are deleted when the browser is closed. Other cookies (so-called persistent cookies) are stored for a specified period of time and are only deleted at the end of this period.
