module OmniAuth
# This simple Rack endpoint that serves as the default
# 'failure' mechanism for OmniAuth. If a strategy fails for
# any reason this endpoint will be invoked. The default behavior
# is to redirect to `/auth/failure` except in the case of
# a development `RACK_ENV`, in which case an exception will
# be raised.
