Persistent cookies, on the other hand, are stored on the user's device for a longer period of time. They have an expiration date and remain on the device until they expire or are manually deleted.
4. First-Party and Third-Party Cookies: First-party cookies are set by the website the user is visiting, while third-party cookies are set by external domains or advertisers that have content embedded on the website. Third-party cookies are often used for tracking user behavior across multiple websites for advertising and analytics purposes.
