In Windows NT, you can have multiple global.asa files by creating an Application Scripting Root for each web. By default, the active global.asa file is the one in the <root web> of the virtual server. The <Root Web> is the location you designate as the home directory in the IIS 4/5/6.0 settings. In NT/2000/2003 server, the global.asa file becomes activated as soon as it is placed in the root folder of the virtual directory. Changes may have a delay associated with the script time out of 15-20 minutes depending on what the administrator has designated. You can access multiple global.asa files in sub-webs if your ISP enables the sub web an an "Application Root". This gives you the ability to have multiple shopping carts in sub-webs but the ability to do this is a normal part of administering the Web Server and has nothing to do with the shopping cart.
