# First, let's import the right kea_connector.
# We have two versions: one for python 2.x and another for python 3.x.
# Sadly, there's no unified way to handle http connections. The recommended
# way is to use Requests (http://docs.python-requests.org/en/master/), but
# that's a stand alone package that requires separate installation. One of
# the design requirements was to not require any additional packages, so
# the code uses standard libraries available in python. Hence two versions.
