HTTP cookies have been a controversial subject for some time. They came into the public eye in recent times when websites were made to start putting notices on their websites asking user’s permission to set them on their system. In the case of many websites, declining this permission means you can’t use the site, so many were left with no choice over what to do. Despite the news coverage given to cookies, very few people understand what they are and what they do.
At the basic level, a cookie is simply a piece of data that a website will send to a user’s computer system or mobile device. They were originally designed, and are still used, to remember previous user activity and actions on a particular website. This proved particularly effective on e-commerce sites. When you click away from an e-commerce site with something in your shopping cart, and then return later to find your product still in the cart, cookies have made that happen.
Cookies are also what enables websites to remember credit card details, addresses, passwords, and anything else that you might enter. Again, when used correctly, these are useful, effective, and convenient for internet users who value ease of use.
