HTTP Headers

Inspect the raw HTTP response headers of a URL.

HTTP Headers Inspector

This tool retrieves and displays the raw HTTP response headers returned by a web server when requesting a specific URL. It performs a HEAD request to securely fetch only the headers without downloading the body content.

Common Headers

  • HTTP Status Code: (e.g. 200 OK, 301 Moved Permanently, 404 Not Found)
  • Server: Identifies the web server software (e.g. nginx, Apache, Cloudflare).
  • Content-Type: Indicates the media type of the resource (e.g. text/html, application/json).
  • Security Headers: Important headers like Strict-Transport-Security, Content-Security-Policy, or X-Frame-Options that protect users.
