IIS/.NET从共享网络驱动器打开/下载文件

IIS 10在使用C时遇到问题,尝试下载位于共享网络驱动器中的文件。

    <preConditions>
      <preCondition name="Excel Example">
        <add input="{HTTP_USER_AGENT}" pattern="Trident" negate="true" />
      </preCondition>
    </preConditions>

   <!-- Sample rules -->
   <rule name="test excel" enabled="true" stopProcessing="true">
      <match url=".*.xlsx" />
      <action type="Rewrite" url="site/{R:0}" />
    </rule>

    <rule name="File Downloads" enabled="true" stopProcessing="true">
      <match url=".*netdrive(.*)" />
      <action type="Rewrite" url="site/{R:3}" />
    </rule>

甚至出站规则:

    <rule name="Allow xlsx to be downloaded" preCondition="Excel Example">
      <match serverVariable="RESPONSE_Content_Disposition" pattern=".*netdrive(.*)" negate="false" />
      <action type="Rewrite" value="https://samplesite.org/netdrive/{R:1}" />
    </rule>

    <rule name="Allow xlsx to be downloaded2" preCondition="Excel Example">
      <match serverVariable="RESPONSE_Content_Disposition" pattern=".*[\/\\]netdrive[\/\\](.*)" negate="false" />
      <action type="Rewrite" value="https://samplesite.org/netdrive/{R:1}" />
    </rule>

从字面上看,在.xlsx文件上没有匹配项。我得到404,最多是http://,但只有404屏幕。。。

Requested URL      http://localhost:80/netdrive/Subfolder1/File.xlsx

Physical Path      C:\inetpub\wwwroot\netdrive\Subfolder1\File.xlsx
