module ActionController::ForceSSL - actionpack-3.2.22 Documentation

# module ActionController::ForceSSL

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.
