title: HTTP 403.9 - Access Forbidden: Too many users are connected
body: <p>I have created an application in VStudio. It ran nicely in debugging mode, but my computer became slower and slower as I worked until it finaly became frozen.
  after I manualy restarted it, the app wasn't running any more in debug and I get this execption in the browser.</p>
  
  <ol>
  <li>Only I am connected right now to the app.</li>
  <li>I have restarted the computer so there coudn't be any instance of a client connected</li>
  <li>I have removed and reinstalled the IIS</li>
  </ol>
