# sample script for sending user defined updates 
# 2014 Christian Schoenebeck <christian dot schoenebeck at gmail dot com>
#
# activated inside /etc/config/ddns by setting
#
# option update_script '/usr/lib/ddns/update_sample.sh' 
#
# the script is parsed (not executed) inside send_update() function
# of /usr/lib/ddns/dynamic_dns_functions.sh
# so you can use all available functions and global variables inside this script
# already defined in dynamic_dns_updater.sh and dynamic_dns_functions.sh
#
# It make sence to define the update url ONLY inside this script 
# because it's anyway unique to the update script
# otherwise it should work with the default scripts
#
# the code here is the copy of the default used inside send_update()
#

__urlencode __PASS "$password"	# encode password, might have special chars for security reason
