HTTP header checker
Inspect response headers, redirect hops and common browser security policy headers.
Requests are made from this website to public HTTP/HTTPS addresses on standard ports, with up to five redirects. No sign-in credentials or cookies are sent. Use public URLs without access tokens or personal query parameters. Cookie values are redacted. HEAD responses may differ from GET; GET bodies are discarded after a small limit. This is a snapshot, not a complete security audit.
