ASP.NET MVC在子文件夹web.config中忽略maxRequestLength和maxAllowedContentLength？

Question

我在子目录（即Areas \ Administration \ Views）中设置了web.config中的maxRequestLength和maxAllowedContentLength（每个20MB）。我在管理文件中上传文件，当我尝试上传大文件（在这种情况下为〜9MB）时，我得到“超出最大请求长度”。如果我将这两个设置移动到根目录，但我宁愿不这样做。有什么建议么？

技术：Windows Server 2008 Enterprise上的ASP.NET，.NET 4.0，MVC 3和IIS 7。

在你的webconfig文件，你需要使用路径声明<位置>标签那样：

<location path="controller/action"> 
    <system.web> 
    <!-- maxRequestLength is in kilobytes (KB) --> 
    <httpRuntime maxRequestLength="5120" /> <!-- 5MB --> 
    </system.web> 
    <system.webServer> 
    <security> 
     <requestFiltering> 
     <!-- maxAllowedContentLength is in bytes (B) --> 
     <requestLimits maxAllowedContentLength="5242880"/> <!-- 5MB --> 
     </requestFiltering> 
    </security> 
    </system.webServer> 
</location>
