Inspect the first HTTP redirect response and Location header returned by a public URL.
About Redirect Checker
Inspect the first HTTP redirect response and Location header returned by a public URL. cURL requests the URL without following redirects so the first status and Location target can be inspected.
How to use Redirect Checker
Enter a public URL and run the checker. ToolFlow intentionally does not follow the redirect, so you can inspect the first status code, Location target and response headers.
When Redirect Checker is useful
- Investigate a public website during development, deployment or SEO review.
- Verify an HTTP, DNS or TLS detail before changing server configuration.
- Capture a point-in-time diagnostic result without installing a local command-line tool.
Practical tips
- Run diagnostics against a public URL you are authorized to test.
- A single request is a point-in-time measurement; network and server conditions can change between checks.
- For production decisions, confirm important findings with server logs or authoritative configuration data.
Redirect Checker FAQ
Does Redirect Checker change my original input?
No. ToolFlow works on a temporary upload or submitted value and returns a separate result. Your local original is not overwritten.
Can Redirect Checker access private or local network addresses?
No. ToolFlow is designed to reject localhost, local domains and private or reserved IP ranges before making a server-side request.
プライバシーとファイル処理
This diagnostic sends a server-side request only to public addresses after private and reserved network ranges are rejected. The destination website may record ToolFlow's server request in its own logs. See the プライバシーポリシー for details.
