asp.net - 是什么导致 IIS 7.5 上传递静态文件时出现 404.4？

Question

我正在尝试将在 IIS7.5 上运行的 ASP.NET 站点上的默认页面设置为 Index.html。我不断收到 404.4，它告诉我未设置处理程序。然而，我有一个<handler>和一个<httpHandlers>为我的 html 页面设置的值。我还指定了默认文档。但我不断收到 404.4。

我可以浏览到 myuri/index.html，但无法将其加载为默认值。

有什么建议吗？

这是我的 web.config

为了在iis 7.5中处理静态内容，您需要通过web.config文件中的以下元素注册mime类型。我主要用于mp4视频，没有它就会出现404.4错误。

<staticContent> 
 <mimeMap fileExtension=".mp4" mimeType="video/mp4" /> 
 <!-- for html may be -->
 <mimeMap fileExtension=".html" mimeType="text/html" /> 

</staticContent>
