The HTTP cookie , invented at Netscape in 1994, came into life as an innocent and essential tool for the web; cookies make possible "stateful" user interfaces such as user accounts and logins, multi-page forms, or online shopping carts. But cookies also allow sites to store a unique ID in your browser, and therefore to track you—and if a company is present on multiple websites, it can track your visits to each of those sites.
