got the damn routing to finally work!

ApplicationController.rb

class ApplicationController < ActionController::Base

  protect_from_forgery                                                                                                       

    #session['user_return_to'] = request.url    
    def after_sign_in_path_for(resource)
      sign_in_url = "http://localhost:3000/users/sign_in" || "http://onvard.com/users/sign_in" || 
      "http://www.onvard.com/users/sign_in" #url_for(:action => 'new', :controller => 'sessions', :only_path => false, :protocol => 'http')                                            
      if (request.referer == sign_in_url)

        session[:current_path] || env['omniauth.origin'] || request.env['omniauth.origin']  || stored_location_for(resource) || root_path       
      else
        request.referer
      end
    end


  private
  def store_location
    if user_signed_in?
    else
    session[:original_page] = request.referer
    session[:current_path] = "http://localhost:3000" + request.fullpath

    puts 'aaaaaaaaa below is page a, which should be missions_path'
    puts session[:original_page]
    puts 'aaaaaaaaaa below should be votes'
    puts session[:current_path]
    end
  end

end

MissionsController.rb

class MissionsController < ApplicationController

  before_filter :store_location
  before_filter :authenticate_user!, :except => [:show, :index] 
  
  def vote_for_mission
    @mission = Mission.find(params[:id])

    puts 'vvvvvvv22 below is original page that should be missions_path, not user sign in'
    puts session[:original_page]

    if @mission.voted_by?(current_user) 
      redirect_to (session[:original_page] || request.referer), alert: 'You already voted on this mission.'
    else
      @mission.increment!(:karma)
      @mission.active = true
      @mission.real_author.increment!(:userpoints) unless @mission.real_author.blank?
      
      current_user.vote_for(@mission)
      redirect_to (session[:original_page] || request.referer), notice: 'Your vote was successfully recorded.'
    end
  end
end
