Trình truy vết chuỗi chuyển hướng

Cách sử dụng công cụ này

1. 1

   Paste or type a URL into the input box (if you omit the scheme, https:// is added automatically).

2. 2

   Click Analyze to send the URL to the tracer.

3. 3

   Read the chain: each numbered row shows the URL it requested and the status code it got back.

4. 4

   Check the final row — a 2xx means the chain resolves; a long chain or an error row flags a problem to fix.
