# The purpose of this file is to do some remapping of the incoming
# tftp requests in the cases where we can identify the incoming client
#  (i.e. in the case of Windows).  This helps us achieve a better organization
#  in the tftp directory structure.
#
# Remap all paths starting with \ to lowercase.  This normalizes
#   all windows tftp requests to lowercase files.
#   We also prefix "\winpe" to the request.
r  ^\\(.*)$ \\\Lwinpe\\\1
# Remap all \ path separators to / (Windows to Unix style)
rg  \\  /
