About the HTTP Header Checker
Enter a URL to fetch its live response headers: the status code, the full redirect chain, content type and encoding, cache-control and expiry, server software and every security header the site sends.
It is the fastest way to confirm an HTTPS redirect, debug a caching problem, verify that HSTS and Content-Security-Policy are actually deployed, or check that a canonical or x-robots-tag header is set the way your SEO plan expects.
