SSL Requirement =============== SSL requirement adds a declarative way of specifying that certain actions should only be allowed to run under SSL, and if they're accessed without it, they should be redirected. Example: class ApplicationController < ActiveRecord::Base include SslRequirement end class AccountController < ApplicationController ssl_required :signup, :payment ssl_allowed :index def signup # Non-SSL access will be redirected to SSL end def payment # Non-SSL access will be redirected to SSL end def index # This action will work either with or without SSL end def other # SSL access will be redirected to non-SSL end end You can overwrite the protected method ssl_required? to rely on other things than just the declarative specification. Say, only premium accounts get SSL. For SSL domains that differ from the domain of the redirecting site, add the following code to development.rb / test.rb / production.rb: # Redirects to https://secure.example.com instead of the default # https://www.example.com. config.after_initialize do SslRequirement.ssl_host = 'secure.example.com' end P.S.: Beware when you include the SslRequirement module. At the time of inclusion, it'll add the before_filter that validates the declarations. Some times you'll want to run other before_filters before that. They should then be declared ahead of including this module. Copyright (c) 2005 David Heinemeier Hansson, released under the MIT license
