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.

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.
