* MODULE: inet.cxx
*
* The module contains routines for the setting up the WWW Printer Service during spooler start up.
*
* The entry point here should be called by localspl\init.c\InitializePrintProvidor() once it is done
* with its work.
*
* Copyright (C) 1996 Microsoft Corporation
*
* History:
* Dec-1996 BabakJ Wrote it for IIS 2.0.
* June-1997 BabakJ Rewrote to use IIS 4.0's new Metabase interface
* Feb-1998 Weihaic Modify the URL in default.htm
* Feb 1999 BabakJ Made metabase interface a global to avoi calling too many CoCreateInstance() for perfrmance.
