Frequently Asked Questions
What is the HttpOnly cookie flag?
HttpOnly prevents JavaScript from accessing the cookie via document.cookie, protecting against XSS-based session hijacking. Always set it on session cookies.
What does SameSite=Strict do?
SameSite=Strict prevents the cookie from being sent with cross-site requests, effectively preventing CSRF attacks. SameSite=Lax is a more permissive option.
