Question 1

What types of redirects can this tool detect?

Accepted Answer

Our redirect checker not only supports standard HTTP status code redirects (like 301 Permanent, 302/307 Temporary) but also features a powerful parsing engine that deeply sniffs hidden redirect behaviors when a page returns a 200 OK. This includes auto-refresh redirects based on HTML Meta Refresh and redirects triggered by JavaScript (e.g., window.location.href), providing you with the most comprehensive redirect path trace.

Question 2

What is the "Global 10-Node Concurrent Probe Network" and why use it?

Accepted Answer

Many complex marketing links or malicious URLs employ a "geo-routing" strategy, meaning users from different countries or regions clicking the same link will be redirected to entirely different final pages. The moment you initiate a check, we simultaneously send real requests from 10 global edge nodes (including the US, Singapore, Japan, Germany, etc.). By comparing the results from these nodes, we help you instantly expose whether the link has "IP-based geo-redirects" or is being intercepted by firewalls.

Question 3

Why do I need to switch User-Agents?

Accepted Answer

Many links practice "device fingerprint routing." For instance, they might show a normal webpage when detecting a desktop visit, but force a redirect to an ad download page when detecting a mobile device, or specifically disguise content for the built-in browsers of social apps like WeChat or WhatsApp. By switching User-Agents at the top of the tool (e.g., Mobile, Desktop, Search Engine Bot, Social Media), you can simulate various environments and expose these device-specific redirect tricks.

Question 4

What does the "Strong Anti-Tracking Detected" warning mean?

Accepted Answer

Certain short link systems (like tmpm.cn) employ extremely strict anti-bot and anti-tracking mechanisms. They not only verify the requesting IP address and device fingerprint but may even forcibly bind the short link to the client that first generated it. When our cloud nodes attempt to resolve such links, they are blocked by the destination's security policies, preventing us from fetching the final target. In these cases, the tool issues a security warning, advising you to open the link cautiously in a real browser.

Question 5

What is URL Stripper?

Accepted Answer

Modern web links often carry a long string of tracking parameters at the end (such as utm_source, fbclid, gclid). These "tails" are primarily used by advertisers to track your click source and behavior, which severely compromises privacy and makes the link bloated. Once the tool successfully resolves the final destination link, our URL Stripper automatically removes these redundant tracking parameters, providing you with a clean, neat, and privacy-protecting original link that is safe to share.
