HTTP Headers & Redirect Checker

How to use the header checker

1. Enter a web address. You can leave out https://; add http:// to test the redirect to HTTPS.
2. Press Check headers.
3. Read the redirect chain, the security grade and the full list of response headers.

We follow up to 10 redirects one by one, so you can see each step. Only public websites on the standard ports can be checked.

Status codes you will see

Redirects and SEO

• Use one 301 redirect from every old address to its final address; chains of several redirects waste time and crawl budget.
• Pick one version of your site (with or without www, always HTTPS) and redirect the others to it.
• Avoid redirect loops, which the checker detects.

Security headers

The grade (A to F) weighs these headers on the final page. Add missing ones in your web server, hosting control panel or CDN.

Frequently asked questions

Why do I get a 403 for a site that works in my browser?

Some sites block requests that do not come from a full browser. The headers shown are still what that server returns to automated clients.

Does the checker see the page content?

No. We read only the status and headers and discard the body.

What does the "server reveals its software" note mean?

Headers like Server or X-Powered-By can show software versions, which helps attackers find known weaknesses. Most servers can hide them.
