Redirect Chain & Hop History
Requests originate from our server with SSRF safeguards. Inspected URLs and response payloads are not stored.
Websites rely on HTTP status codes to communicate request outcomes. A 200 OK means success, a 301 Moved Permanently signals canonical SEO relocation, a 404 Not Found warns of missing assets, and a 500 error alerts you to server-side crashes.
This tool checks any public URL, measures server latency in milliseconds, detects the negotiated protocol (HTTP/1.1 or HTTP/2), and visualizes the complete redirect chain hop by hop.
How to use this tool
- Enter the target URL (e.g., https://example.com or http://example.com).
- Click Check URL to dispatch the request.
- Inspect the final status code, response time, and the step-by-step redirect hop chain.
Why redirect chains harm SEO and performance
A redirect chain occurs when a URL passes through multiple intermediate hops before reaching its destination (for example, http://site.com -> https://site.com -> https://www.site.com -> https://www.site.com/).
Each redirect adds a full round-trip TCP and TLS handshake, increasing load time on mobile devices and wasting search engine crawl budgets. This tool reveals every hop so you can configure single-hop redirects.
Engineered with strict SSRF protection
Server-Side Request Forgery (SSRF) occurs when a web diagnostic tool is coerced into requesting private internal resources. ToolDuck re-resolves and validates the destination IP before every redirect hop, blocking loopback (127.0.0.1), private networks (10.x, 172.16.x, 192.168.x), and cloud metadata endpoints.
Frequently asked questions
What is the difference between a 301 and a 302 redirect?
A 301 Moved Permanently tells browsers and search engines to update their bookmarks and transfer SEO link equity to the new address. A 302 Found indicates a temporary relocation where the original URL should be preserved.
What is the maximum number of redirects followed?
The tool follows up to 5 consecutive redirects to prevent infinite redirect loops.
