Professional HTTP Header Viewer

Our HTTP Header Checker is a powerful tool for web developers, SEO specialists, and security researchers. It allows you to inspect the raw "handshake" between a client and a server for any URL.

What are HTTP Headers?

HTTP headers provide essential information about the server, the content type, caching policies, and security settings. By checking headers, you can verify if your site is using **HTTPS**, if **HSTS** is enabled, and if your **Cache-Control** settings are optimized for performance.

Debug Server Responses

Simply enter a URL and hit "Check Headers" to see the status code (e.g., 200 OK, 301 Redirect, 404 Not Found) and the full list of headers returned by the server. This is crucial for troubleshooting redirects and server-side errors.
