title: Read a web.config file in a virtual directory
body: <p>I have an ASP.NET application (Root Application) that has a virtual directory set up to another ASP.NET application (Virtual Application).  How can I make the Virtual Application read values from the Root Application's web.config file?  I was looking at the WebConfigurationManager.OpenWebConfiguration() class, but I'm unsure how how to tell it to go up one level from the root.  For example, I would tell it to go to ~/web.config to get the the Virtual Application's web.config file, but I need it to go up one more level to the Root Application's file structure.  Is this even the correct approach?</p>
  
  <p>Any help would be greatly appreciated!!</p>
