More on the topic: Cookies
Even if the term "cookie" generally leads to associations with sweet pastries, a cookie in surfing has nothing to do with a cookie snack while surfing. The electronic namesake is Center of many disputes, and despite the innocent name many users are cookies skeptical vis-à-vis.
What is a cookie/cookies? What does "set cookies" mean?? Why does a cookie message appear recently when a page is visited?? Should I agree or disagree with cookies? The following Guidebook answers these questions and gives you a Overview of the topic.
