Android 上的 Chrome 發出數十個相同的 HTTP 請求

我在 HTTP 存取日誌中看到奇怪的模式。有時，行動 Chrome 瀏覽器會發出數十個看似多餘的 HTTP 請求來取得相同頁面。

什麼可能導致這種行為？

  • 使用預設用戶代理字串的有缺陷的應用程式？
  • 瀏覽器錯誤？似乎不太可能，因為這至少跨越 Chrome 34 到 45。
  • 安卓的bug？出於同樣的原因似乎不太可能（至少 4.4.4 到 5.1.1）。
  • 網站上的一些東西，例如。導致重定向的 JS 程式碼 - 但僅在這些用戶代理上？這種情況在多個網站上都發生過（儘管具有相同的 CMS），但超過 99% 的網站沒有顯示此行為。
  • 用戶是故意的嗎？你如何用觸控螢幕每秒按 20 次重新載入？ :)（當然可以有藍牙鍵盤，但似乎不太可能）
  • 還有別的事嗎？

這是一次日誌摘錄。一個 IP 位址，匿名：（時間、回應碼、請求、引薦來源網址）
