HTTP Headers

View a URL's response headers and follow its redirect chain.

Frequently asked questions

What are HTTP response headers?

They are metadata a web server returns with each response — things like Content-Type, Cache-Control, Server, Set-Cookie and security headers. They control caching, security and how browsers handle the page.

Does this follow redirects?

Yes. It shows the full redirect chain with the status code at each hop and the headers of the final response.

Why would I inspect headers?

To debug caching, redirects, CORS, cookies and compression, and to confirm a server is returning the configuration you expect.
