module ActionController
# This module provides a method which will redirect browser to use HTTPS
# protocol. This will ensure that user's sensitive information will be
# transferred safely over the internet. You _should_ always force browser
# to use HTTPS when you're transferring sensitive information such as
# user authentication, account information, or credit card information.
#
# Note that if you are really concerned about your application security,
# you might consider using +config.force_ssl+ in your config file instead.
# That will ensure all the data transferred via HTTPS protocol and prevent
# user from getting session hijacked when accessing the site under unsecured
# HTTP protocol.
