What this tool shows

OrbitProbe requests the home page over HTTPS, follows redirects and lists the headers of the final response exactly as the server sent them. Headers are how a server tells browsers and caches what to do: how long to keep a copy, whether the page may be framed, which scripts may run, and that the site must only be reached over HTTPS.

Cookie values are never displayed. A Set-Cookie header can carry a session identifier, so only the cookie name and its attributes (Secure, HttpOnly, SameSite, expiry) are shown. Those attributes are the part worth reviewing anyway.
