What this inspection tells you

Use this tool to inspect a public page’s response status, redirect chain, HSTS and cache policy, compression header, and the HTTP/1.x or HTTP/2 version negotiated from this server. HTTP/3 is not probed. Results explain the status, cache behavior and HSTS observation, with next steps; they do not verify page content, CSP or a browser’s stored policies.

HEAD requests read headers only. GET requests stop reading after 64 KiB; the body is never displayed or retained. At most five redirects are followed, within a shared five-second deadline. A redirect to a private or blocked target, credentials, or a query string stops the inspection.

The request sends no cookies or authorization values and uses no inherited proxy. Cookie and authentication response values and headers outside a small safe list are redacted. Results describe this server’s request, which can differ from your browser.
