# Redirect the current site visitor to another page if she/he
# is not authenticated.
# More information about the authentication feature here:
# https://locomotive-v3.readme.io/v3.3/docs/introduction-1
#
# The Liquid tag requires 2 parameters:
# - the slug of the content type used for the authentication (a content type with a password field)
# - the handle of the page we want the user to be redirected to if unauthenticated
#
# Basically the authorize tag checks if the liquid context has
# a reference to the current authenticated content entry.
# If not, it raises a redirection exception forcing the Steam middleware stack
# to process a HTTP redirection.
#
# Example:
#
# {% authorize 'accounts', 'sign_in' %}
#
