Record your rack/rails requests and store them for future inspection + see them in your chrome console.

Install

gem install request_recorder

Add to your middleware stack:

require "request_recorder"

require "request_recorder/cache_logger"
use RequestRecorder::Middleware,
  :store => RequestRecorder::CacheLogger.new(Rails.cache),
  :frontend_auth => lambda { |env| Rails.env.development? } # TODO use something like `env.warden.user.is_admin?` in production, or return a [status, headers, body] array for custom failure message
  # if you get 502's because of too large headers, you can reduce them: everything in :remove will be removed when above :max
  # :headers => {:max => 10_000, :remove => [/Identity Map/, /Cache local read/, /Cache read/, /SELECT count(\*)/, /SELECT \* FROM/] }
