Cucumber remove Rack::Cache logging

I am using a cucumber and capybara-webkit in a project that uses Dragonfly.
When I used capybara-webkit I suddenly started getting some Rack::Cache debug log. Which looked like the following,

 @javascript
  Scenario: Save new event as draft                               # features/manage_events.feature:23
cache: [GET /user/sign_out] miss
cache: [GET /] miss
cache: [POST /user/sign_in] invalidate, pass
cache: [GET /events/new] miss

cache: [PUT /users/update_time_zone] invalidate, pass
    When I fill in "Event Name" with "Event 1"                    # features/step_definitions/web_steps.rb:3
    And I fill in "Event Description" with "This is a test event" # features/step_definitions/web_steps.rb:3
    And I fill in "Event Venue" with "Dhaka, Bangladesh"          # features/step_definitions/web_steps.rb:3
    And I press "Search"                                          # features/step_definitions/web_steps.rb:7
cache: [GET /events/location_search?str=Dhaka,%20Bangladesh] miss
    And I fill in "Event Start date" with "2012-05-22"            # features/step_definitions/web_steps.rb:3
    And I fill in "Event End date" with "2012-05-23"              # features/step_definitions/web_steps.rb:3
    And I press "Save as draft"                                   # features/step_definitions/web_steps.rb:7
cache: [POST /events/4fbc72688621ff1a31000026] invalidate, pass
cache: [GET /my/events?p=false] miss
cache: [GET /assets/ui-bg_glass_65_ffffff_1x400.png] miss
cache: [GET /assets/bg.gif] miss
    Then I should see "Event was successfully updated."           # features/step_definitions/web_steps.rb:11

That log comes from the Rack::Cache which is used by Dragonfly. So you can add the following code snippet in the test.rb,

  require 'rack/cache'
  config.middleware.delete ::Rack::Cache
  rack_cache_already_inserted = Rails.application.config.action_controller.perform_caching && Rails.application.config.action_dispatch.rack_cache

  Rails.application.middleware.insert 0, Rack::Cache, {
      :verbose => false,
      :metastore => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/meta"), # URI encoded in case of spaces
      :entitystore => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/body")
  } unless rack_cache_already_inserted
