You can achieve this by overriding the HighVoltage#PagesController
see the override section of the documentation.
It might look something like this:
class PagesController < ApplicationController
include HighVoltage::StaticPage
before_filter :ensure_secure_page
private
def ensure_secure_page
if params[:id] == 'contact'
# check to make sure SSL is being use. Redirect to secure page if not.
end
end
end
Next disable the routes that HighVoltage provides:
# config/initializers/high_voltage.rb
HighVoltage.routes = false
Then in your application's routes file you'll need to set up a new route:
# config/routes.rb
get "/pages/*id" => 'pages#show', as: :page, format: false
