title: .Net Core with IIS getting 404 on Root Folder
body: <p>I have an issue with our .net Core API.
  We found out, that we recieve every 10 Minutes a call against our root folder from IIS Website. But we do not recieve the call from an external application:
  I can see in our logging framework (Application Inisghts) that the call is against localhost: <a href="http://localhost/test/MyTestApp/" rel="nofollow noreferrer">http://localhost/test/MyTestApp/</a>  </p>
  
  <p>I can see the folling information in the logs:</p>
  
  <ul>
  <li>AspNetCoreEnvironment : Production</li>
  <li>Host : localhost</li>
  <li>LoggerName : Microsoft.AspNetCore.Hosting.Internal.WebHost</li>
  <li>Method : GET</li>
  <li>Path : /test/MyTestApp/</li>
  <li>Protocol : HTTP/1.1</li>
  <li>Scheme : http</li>
  </ul>
  
  <p>It seems like the IIS is calling the root folder every 10 minutes by self.
  But thats only happening with the .Net Core API.</p>
  
  <p>The IIS Looks like this:</p>
