title: Override web.config in ASP.NET sub-application
body: <p>IIS 7 .NET 4.0
  I have a website with 4 sub-web-applications.
  3 of them need settings from the parent-web.config
  One should have a completely independent web.config (no inheritance)
  I am aware of the possibility to turn off inheritance for sub-apps.
  But what I need is a way to turn it off for only one sub-app! (without having to  each section individually..
  So I am looking for something like a "dontInheritParentConfig" setting in my sub-web.config</p>
  
  <p>Thank you!</p>
