HTTP Header Checker

HTTP Header Checker gives a quick look at how a URL responds before loading the full page. It helps spot redirects, errors, caching behavior, and server-side clues.

What It Shows

  • HTTP status code.
  • Redirect chain behavior.
  • Response headers.
  • Server and cache hints when exposed.
  • Basic TLS and final URL clues.

When It Helps

Use it when a website redirects unexpectedly, returns a 403/404/500, behaves differently after DNS changes, or needs quick confirmation from outside your network.

Follow-Ups

  • Use SSL / TLS Certificate for certificate-specific issues.
  • Use DNS Lookup for host resolution.
  • Use Port Checker if the server does not connect at all.
