Quick hack: A Capybara that you can tell not to auto-follow redirects

my_spec.rb

it "does not have to auto-follow redirects", :driver => :tito_driver do
  page.driver.stop_following_redirects

  # make a web request that redirects
  # do whatever you need to do
  # the continue...

  page.driver.follow_redirects!
end

stop_following.rb

# I put this in spec/support/
class Tito::Driver < Capybara::RackTest::Driver
  def initialize(app, options = {})
    super

    @follow_redirects = true
  end

  def browser
    @browser ||= Tito::Browser.new(self)
  end

  def follow_redirects?
    @follow_redirects
  end

  def follow_redirects!
    @follow_redirects = true
    browser.follow_redirects!
  end

  def stop_following_redirects
    @follow_redirects = false
  end
end

class Tito::Browser < Capybara::RackTest::Browser
  def follow_redirects!
    super if driver.follow_redirects?
  end
end

Capybara.register_driver :tito_driver do |app|
  Tito::Driver.new app
end
