ASP.NET MVC sono maxRequestLength e maxAllowedContentLength ignorati in una sottocartella web.config?

Question

Ho entrambi maxRequestLength e maxAllowedContentLength impostati in web.config (20 MB ciascuno) in una sottodirectory (ovvero Aree \ Amministrazione \ Visualizzazioni). Ho caricato i file all'interno dell'amministrazione e quando provo a caricare un file di grandi dimensioni (~ 9 MB in questo caso) ottengo "La lunghezza massima richiesta superata". Se sposto le due impostazioni alla radice funziona, ma preferirei non farlo. Eventuali suggerimenti?

Tecnologia: ASP.NET, .NET 4.0, MVC 3 e IIS 7 su Windows Server 2008 Enterprise.

Nel file WebConfig, è necessario dichiarare la <posizione> tag con il percorso in questo modo:

<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>
