Module Name:

    autoprox.hxx

Abstract:

    Contains interface definition for a specialized DLL that automatically configurares WININET proxy
      information. The DLL can reroute proxy infromation based on a downloaded set of data that matches
      it registered MIME type.  The DLL can also control WININET proxy use, on a request by request basis.
