Header HTTP & Rantai Redirect

This tool helps you troubleshoot web requests by showing the full redirect chain and response headers for each hop. It’s useful when a URL unexpectedly redirects, a CDN caches the wrong response, or you need to verify security headers like HSTS, CSP, and frame protections.

Paste a URL and the tool follows redirects and displays status codes, locations, and key headers per hop. This makes it easy to spot mixed HTTP/HTTPS issues, missing canonical redirects, wrong hostnames, or unexpected middleware behavior.

For reliable debugging, compare the final destination with what your browser shows and check whether intermediate hops return cache headers or set cookies. If you’re deploying SEO changes, this view also helps verify 301/302 behavior and canonical paths.

Common use cases include: validating canonical 301s after a migration, checking whether non-www → www rules are in place, and ensuring HTTPS is enforced without looped redirects. It also surfaces cache headers (Cache-Control, ETag, Age), so you can see if a CDN or reverse proxy is serving stale content.

Security teams can quickly confirm HSTS, CSP, frame-ancestors, X-Content-Type-Options, and referrer policies on the final response. DevOps can copy a ready-to-run curl command for each hop to reproduce issues locally. Product owners can verify that marketing redirects (UTM → landing) hit the right target without extra hops.

Long-tail checks you can solve here: “check http header online”, “follow redirect chain”, “301 302 tester”, “cache-control header checker”, “HSTS CSP verifier”, “canonical redirect checker”, “security header scan”, “copy curl with redirects”. Use the copy buttons to lift the exact URL, Location, headers or curl so you can paste them into tickets, monitoring, or CI tests.
