什麼是HTTP狀態碼檢查工具？
HTTP狀態碼告訴你一個請求是成功、重新導向還是失敗了。最重要的幾個類別：2xx（成功）、3xx（重新導向）、4xx（用戶端錯誤：404 Not Found、403 Forbidden）、5xx（伺服器錯誤：500 Internal Server Error、503 Service Unavailable）。監控狀態碼可以發現失效的頁面、設定錯誤的重新導向以及伺服器當機。
常見使用場景
Confirm a page returns 200 OK after deploying a change or fixing a broken link.
Verify that an old URL ends at the right destination after setting up redirects for a site migration.
Diagnose why a link is failing by seeing whether it returns 404, 403, 401, or a 5xx error.
Spot-check that a server is reachable over HTTPS rather than only plain HTTP.
Test whether a third-party API endpoint or webhook URL responds before wiring it into your code.
Check competitor or partner URLs for outages or moved pages without installing any software.
