Hi Mike,
The
=============== ==
Configuration File
This element can be used in the application configuration file, machine
configuration file (Machine.config ), and Web.config files that are not at
the application directory level.
=============== ==
in the MSDN reference is focus on asp.net configuration scenario. Every
asp.net web application (in IIS) will be hosted in an Virutual dir which is
configured as "Applicatio n". And this virtual dir is called the root
directory of the asp.net web application.( there may exists many hierarchy
of sub dirs under it). And we can put web.config file in both root dir or
sub dir( roor dir's web.config is not optional). However, not all those
xml config element are allowed to used in the sub dir's web.config, some
are only allowed to appear once for each asp.net web application (in the
root dir's web.config). That's why each config element in MSDN 's schema
reference will have the above notes.
=============== ==
Configuration File
This element can be used in the application configuration file, machine
configuration file (Machine.config ), and Web.config files that are not at
the application directory level.
=============== ==
this means that this element can be used not only in asp.net application's
root dir's web.config but also in subdir's web.config file.
If there is still anything unclear, please feel free to post here. Thanks.
