//
/// Setup the Symple server

var Symple = require('symple');
var sy = new Symple();

/// Setup the client web server

var express = require('express'),

  app = express(),
  serverPort = parseInt(sy.config.port)
  clientPort = serverPort - 1;

  // NOTE: This method of generating unique tokens is not secure, so don't use
  // it in production ;)
  var token = '' + Math.random();

  // Create the arbitrary user session object here
  var session = {
    // user: 'demo',
    // name: 'Demo User',
    group: 'public'

  // Store the user session on Redis
  // This will be sent to the Symple server to authenticate the session
  client.set('symple:session:' + token, JSON.stringify(session), redis.print);

  // Render the response
