web.config files configure
applications hierarchically -- i.e., an application can contain
more than one web.config file,
with each file residing in a separate folder of the application.
Settings in a web.config file in
a child folder of the application root override the settings of
the
web.config file in the parent folder.
Settings not defined in the child web.config file inherit the settings from the
parent web.config file. Figure 20-1 demonstrates these rules of precedence.

In addition to inheriting settings from a web.config file defined in a parent folder,

called machine.config. The
machine.config file contains
