title: Control upload file size using web.config
body: <p>I need to control upload max file size per folder in my asp.net mvc app. So I have in root web.config </p>
  
  <pre><code>&lt;system.web&gt;
    &lt;httpRuntime maxRequestLength="1024" /&gt;
  &lt;/system.web&gt;
  </code></pre>
  
  <p>and then I have upload folder structure as such
  Uploads-
          User1
          User2
  So I added web.config for user 1 folder where I set maxRequestLength to 20480. But it does not effect my app. It looks like my overrides not effect my app.
  Any suggestions???</p>
