cookie_monster.rb

module Agora
  class CookieMonster
    def initialize(app)
      @app = app
    end

    def call(env)
      path = env["PATH_INFO"]
      response = @app.call(env)
      response[1].delete('Set-Cookie')

      return response
    end
  end
end

Add the following in config/environment.rb:

insert middleware to strip Set-Cookie response headers for requests

require 'lib/agora/cookie_monster'
config.middleware.insert_before(ActionController::Session::CookieStore, Agora::CookieMonster)
