The Cookie Protocol

HTTP Cookies are small blocks of data created by a web server while a user is browsing a website and placed on the user's computer or other device by the user's web browser. They are used for session management, personalization, and tracking.


SameSite Policy: This attribute allows servers to assert that a cookie ought not to be sent along with cross-site requests, which provides some protection against cross-site request forgery (CSRF) attacks.

Security Note: Always use the `Secure` attribute to ensure cookies are only transmitted over encrypted connections (HTTPS). The `HttpOnly` flag prevents client-side scripts from accessing the cookie, mitigating XSS risks.
