The
App_Browsers
folder holds
browser files
, which are
XML
files used to describe
characteristics and capabilities
of these browsers. We can find a
list of globally
accessible browser files in the
CONFIG\Browsers
folder under the
installation
path. In addition, if you
want to change
any part of these default browser definition files, just
copy the appropriate browser file
from the Browsers folder to
your applications\App_Browsers
folder and change the definition.
