Play • 18 min

Cookies are primarily used on the Web for two things: authentication and tracking. Although alternatives exist, cookies are the most popular way to provide some state for the stateless HTTP protocol. In this episode we explain what cookies are, how they work, the origin of cookies, applications of cookies, which browsers block "bad" cookies to protect your privacy, first-party versus third-party cookies, and why you need to click those popups about cookies on almost every website you visit.
