Android 上的 Chrome 发出了数十条相同的 HTTP 请求

我在 HTTP 访问日志中发现了一种奇怪的模式。有时，移动版 Chrome 浏览器会发出数十个看似多余的 HTTP 请求来获取同一页面。

什么可能导致这种现象？

  • 使用默认 User-Agent 字符串的错误应用程序？
  • 浏览器错误？不太可能，因为这至少涵盖了 Chrome 34 到 45。
  • Android 错误？出于同样的原因，似乎不太可能（至少 4.4.4 到 5.1.1 是这样的）。
  • 网站上的某些内容（例如 JS 代码）会导致重定向 - 但仅限于这些用户代理？这种情况发生在多个网站上（尽管具有相同的 CMS），但超过 99% 的网站没有显示此行为。
  • 用户，故意的？你怎么能用触摸屏每秒按 20 次重新加载？:)（当然，可以使用蓝牙键盘，但似乎不太可能）
  • 还有别的吗？

以下是某次事件的日志摘录。一个匿名 IP 地址：（时间、响应代码、请求、引荐来源）
