Cookie

Cookie, also known as anHTTP cookie, web cookie, or browser cookie, is a small piece of data sent from a website and stored in the user’s web browser while the user is browsing, allowing the website or server to uniquely identify the browser or track user activity. When the browser is closed, the cookie is deleted and will no longer be accessible.

Cookies are useful for many online services, such as keeping users logged in, remembering user preferences and settings, and tracking user behavior. It can also be used to customize content or advertisements for users.

When a user visits a website, the web server sends a cookie to the user’s browser. The browser stores and sends the cookie back to the server every time the user makes a request. When the server receives the cookie, it can use it to identify the user’s previous requests in order to provide a consistent and personalized experience.

Cookies can also be used for malicious purposes, such as tracking user activity and gathering personal information or data. Many web browsers allow users to disable or delete cookies, and in some countries, such as the European Union, websites must provide users with clear instructions on how to do so.

Additionally, developers can take steps to protect users’ privacy by using secure and encrypted cookies, or even by not using cookies at all.

In summary, cookies are small pieces of data stored in a user’s web browser that can be useful for providing better user experience, but can also be used for malicious purposes.
