Question

我有一个在Azure App Service上运行的Node.js（Express）应用程序。每隔一段时间，当我访问我的域，而不是执行Node应用程序时，我将被带到https://example.com/server.js。这种情况并不经常发生，但偶尔我们会有一份用户报告说他们无法访问我们的应用，这最终成了罪魁祸首。

更糟糕的是，复制是非常困难的，如果不是不可能的话。我通过全新的浏览器安装再现了一些运气，但并非总是如此。

我基本上使用默认的web.config，并为HSTS / HTTPS添加了几行。见下文：

      You can control how Node is hosted within IIS using the following options:

        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled

有关为何可能发生这种情况的任何建议？

我建议您通过Azure portal安装名为<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <button id="slideRightButton">Slide Right</button> <button id="slideLeftButton">Slide Left</button> <p>By default, all HTML elements have a static position, and cannot be moved. To manipulate the position, remember to first set the CSS position property of the element to relative, fixed, or absolute!</p> <div id="boxToBeMoved" style="background:#98bf21;height:100px;width:100px;position:absolute;"></div>的扩展名，而不是手动添加规则。

azure上的节点应用程序偶尔会重定向到server.js
