+module ActionController
+  # This module provides a method which will redirects 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 really concern about your application safety, you might
+  # consider using +config.force_ssl+ in your configuration 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.
