Frequently asked questions
What is a Cookie header?
▾
An HTTP request header sent by the browser containing all cookies for that domain, formatted as semicolon-separated name=value pairs: Cookie: session=abc123; theme=dark.
What is the difference between a session cookie and a persistent cookie?
▾
Session cookies have no expiry date and are deleted when the browser closes. Persistent cookies have an Expires or Max-Age attribute and survive browser restarts.
What does HttpOnly mean?
▾
HttpOnly prevents JavaScript from accessing the cookie via document.cookie. It protects auth tokens from XSS attacks — the cookie is only sent in HTTP requests, never readable by client-side scripts.
