appcmd.exe to List IIS配置部分属性正在返回错误消息：未知属性

Question

在高架提示中运行此命令：

%systemroot%\system32\inetsrv\appcmd list config "website" /section:requestFiltering /text:AllowDoubleEscaping

返回错误消息：错误（消息：未知属性““ allowDoubleScaping”“”。替换为 - ？寻求帮助。

我

%systemroot%\system32\inetsrv\appcmd set config -section:requestFiltering -?

它 ，我可以看到缺少允许doubleScaping

，因此AppCMD实际检查哪些文件？我继续检查C：\ Windows \ System32 \ inetsrv \ config \ schema \ iis_schema.xml文件，它确实在其中定义了此属性。这似乎是定义的唯一位置，所以我很困惑它在其他地方找不到以抛出错误的属性？

<sectionSchema name="system.webServer/security/requestFiltering">
    <attribute name="allowDoubleEscaping" type="bool" defaultValue="false" />
    <attribute name="allowHighBitCharacters" type="bool" defaultValue="true" />
    <attribute name="unescapeQueryString" type="bool" defaultValue="true" />
