How to check HTTPS redirects

Why this matters

Redirects are common and useful, but they sit in the request path for every visitor. If a redirect points to the wrong hostname, drops an important path, creates a loop, or lands on a certificate problem, users may never reach the intended page.

Search engines also care about redirects because they use them to understand canonical URLs and moved content. Too many hops or inconsistent redirects can waste crawl time and make troubleshooting harder.

Step-by-step instructions

Start with the URL or hostname users enter. Check whether it returns a redirect status such as 301, 302, 303, 307, or 308. Record the Location value, follow it, and repeat until you reach a non-redirect response or hit a loop.

Then inspect the final result. A healthy redirect usually ends at the expected HTTPS URL with a 2xx status. If it ends at a 4xx or 5xx status, the redirect path works but the destination still has a problem.

• Check the starting hostname over HTTPS.
• Record each redirect status code and destination.
• Confirm the chain is short and intentional.
• Confirm the final URL uses the expected hostname and path.
• Check for TLS errors, timeouts, and server errors at the final destination.

Common problems

Redirect loops are the classic failure. They often happen when a CDN, reverse proxy, or application all try to force HTTPS or canonical hostnames in conflicting ways. The browser keeps bouncing between URLs until it gives up.

Other common problems include redirecting to the wrong environment, stripping query parameters, losing path information, or redirecting to a hostname with a certificate mismatch. Those issues can appear after framework changes, CDN rule edits, or domain migrations.

How to read the result

Start with the first status code. A 301 or 308 usually means a permanent redirect. A 302 or 307 usually means a temporary redirect. Then read the Location destination and ask whether it is the intended next URL. If the same URLs repeat, you likely have a loop. If each hop changes only slightly, you may have overlapping canonicalization rules.

The final URL matters most for users. It should use HTTPS, the expected hostname, and the expected path. The final status should normally be a successful 2xx response or an intentional result such as a login page. If the final status is 404 or 500, the redirect chain may be working while the destination is still broken.

Practical redirect checklist

Redirect checks are easiest to debug when you inspect the chain one hop at a time. Do not only look at the final page in a browser. Record each status code and destination so you can find the rule that introduced the wrong hop.

• Start with the URL users enter.
• Confirm each hop is intentional.
• Keep the chain short.
• Preserve important paths and query strings.
• Confirm the final HTTPS URL returns a healthy status.

How to prevent redirect problems

Keep redirect rules simple and documented. Decide one canonical hostname and protocol, then make every alternate entry point move there directly. Avoid stacking rules across multiple systems unless each layer has a clear job.

Test redirects after DNS, CDN, hosting, and framework changes. A redirect that worked in staging may behave differently in production if proxy headers or TLS termination are different.

How Website Certs can help

Website Certs provides a free HTTPS checker that reports status code, response time, final URL, redirect chain, TLS errors, and timeout problems for public hostnames. It gives you a quick way to see where a request really ends.

For ongoing monitoring, Website Certs can watch HTTPS health and pair it with SSL and DNS checks. That helps catch situations where a redirect change sends traffic to a hostname with the wrong certificate or to an unhealthy endpoint.
