HTTP response header viewer

Cache-Control, CSP and CORS mistakes show up in headers, not in HTML. This viewer lists response headers for a public URL so you can debug cookies, compression and security policies.

The same SSRF protections as the status checker apply. Compare headers before and after a deploy of Apache or Nginx.

Look for missing HSTS, overly long cache on HTML, or Access-Control-Allow-Origin: * on cookie APIs.
