Answer 1

class ApplicationController < ActionController::Base
  after_action :set_latest_pages_visited

  def set_latest_pages_visited
      return unless request.get?
      return if request.xhr?

      session[:latest_pages_visited] ||= []
      session[:latest_pages_visited] << request.path_parameters
      session[:latest_pages_visited].delete_at 0 if session[:latest_pages_visited].size == 6
  end
....

and later you can do

  redirect_to session[:latest_pages_visited].last

class ApplicationController < ActionController::Base
  before_filter :store_history

private

  def store_history
    session[:history] ||= []
    session[:history].delete_at(0) if session[:history].size >= 5
    session[:history] << request.url
  end
end
