Fetch Website Response Headers

Fetch a URL's HTTP response headers server-side (use HEAD, fall back to GET). Process: send HEAD, follow redirects, collect headers, block private hosts. Example: inspect CORS, Cache-Control, and Strict-Transport-Security headers to debug redirects and CDN settings.

Notes

  • Some sites do not support HEAD; we will fall back to GET.
  • For safety, requests to localhost/private networks are blocked.

What: Fetch and inspect a website's HTTP response headers. Useful for debugging CORS, caching, redirects and verifying security or CDN headers. Scenarios: developer debugging, SEO checks, and verifying server configuration.
