Redirect & HTTP header checker
Trace redirect chains and review headers when you change lesson paths or course landing URLs.
Page or redirect URL
Follows redirects server-side and records status codes and headers—useful when migrating lesson or course URLs.
Frequently asked questions
- What is this for?
- When you move course pages or consolidate lesson URLs, you want clean redirects and predictable headers. This tool follows redirects and shows status codes and response headers at each hop.
- Why might HEAD fail?
- Some hosts only allow GET. We retry with GET when HEAD is not supported.
- Can I test localhost?
- No. Requests are limited to public hosts for safety—use your deployed staging URL instead.
