HTTP Header Viewer

Request any web address and see exactly what the server sends back: the status code, every redirect step, all response headers, timing, and a security grade for the headers that protect your visitors.

Try:

What are HTTP headers?

Headers are the extra lines a server sends with every page - they say what type of content it is, how long to cache it, which server software runs it, and which security rules the browser should enforce.

Which security headers matter most?

Strict-Transport-Security (forces HTTPS), Content-Security-Policy (limits where scripts can load from), X-Frame-Options (stops clickjacking), X-Content-Type-Options and Referrer-Policy. The tool grades these and tells you what is missing.

How do I fix a redirect chain?

Each redirect adds delay. Aim for at most one hop - for example http://example.com straight to https://example.com - and link to the final address everywhere. The request path section shows every step and its timing.

Does it follow redirects?

Yes, up to 8 steps. Each step is shown with its own status, headers and timing, and the final step is what visitors actually get.
