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

Question

我在子目录(即Areas\Administration\Views)中的web.config(每个20MB)中设置了maxRequestLength和maxAllowedContentLength.我在管理中上传文件,当我尝试上传大文件(在这种情况下约为9MB)时,我得到"超出最大请求长度".如果我将两个设置移动到root它可以工作,但我不想这样做.有什么建议？

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

在您的webconfig文件中,您需要使用以下路径声明<location>标记:

<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>
