■ Local_Drive:\Inetpub\wwwroot—This Web.config file defines configuration
settings for all virtual servers that are on the server. This file is created when a
virtual server is extended.
■ Local_Drive:\Inetpub\wwwroot\wpresources—This Web.config file defines
configuration settings for Web Parts. This file is created when a virtual server is
extended.
■ Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\wpresources—This folder is used to store Web Part file resources
for assemblies that are placed in the Global Assembly Cache (GAC). The purpose
of this Web.config file is to places restrictions on files placed in this folder.
■ Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\60\CONFIG—This Web.config file along with other .config files
define configuration settings for extending other virtual servers.
■ Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\60\ISAPI —This web.config file defines configuration settings for
the /_vti_bin virtual directory. This folder holds Web services used by Windows
SharePoint Services.
■ Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\60\TEMPLATE\LAYOUTS—This Web.config file defines configuration
settings for the _layouts virtual directory. The _layouts directory is used to
hold trusted application pages that should run in direct mode. Anything placed
in the _layouts directory is accessible by all virtual servers on a front-end Web
server.
■ Local_Drive:\Program Files\Common Files\Microsoft Shared\Web Server
Extensions\60\TEMPLATE\ADMIN\Locale_ID—This Web.config file defines
configuration settings for pages used in the virtual server that contains the
SharePoint Central Administration site.
The \60\CONFIG folder contains .config and .xml files that are used together to
create the Web.config file for a virtual server when it is extended with Windows Share-
Point Services. Before copying the Web.config file from the \60\CONFIG folder to the
root folder of the virtual server, Windows SharePoint Services searches the \60\CON-
FIG folder for any .xml file with a name in the format Webconfig.*.xml and merges its
contents with the Web.config file before writing the resulting Web.config file to the
root path of the virtual server. The actions defined in the .xml file are applied to the
configuration settings of the virtual server. A major advantage to using an .xml file to
supplement the Web.config file is that customizations are not lost when Windows
SharePoint Services is upgraded and the Web.config file is overwritten.
