FAQ
What should I know about SameSite=None?
Modern browsers usually require SameSite=None together with Secure, or the cookie may be rejected.
Can I put the result directly into a response header?
The tool outputs a Set-Cookie example. Real delivery still must match domain, path, and security policy.
