Spork.prefork do
  require 'cucumber/rails'
  require 'factory_girl_rails'
  require 'factory_girl/step_definitions'
  require 'database_cleaner'
  require 'database_cleaner/cucumber'
  Capybara.default_selector = :css
  Capybara.default_driver = :selenium
  Capybara.server_port = "9887"
  Capybara.default_host = "http://www.lvh.me"
  Capybara.app_host = "http://www.lvh.me:9887"
  DatabaseCleaner.strategy = :truncation
  ActiveSupport::Dependencies.clear
end

But then in the tests:

(rdb:1) new_user_session_url
"http://www.example.com/users/sign_in"

so of course it tries to go to the wrong place when I visit new_user_session_url, anyone know how to get around this?

Instead of Capybara.app_host try adding Capybara.server_host?
