RedisStore session and Socket.IO

[grigio]

Hi, I'd like to use redis as persistent sessionStore inside Socket.IO, probably I'm missing something because if I write the sessionStore from inside socket.io it is written in the memory store and not in redis.

some code parts:

express    = require 'express'
http       = require 'http'
redis      = require 'redis'
connect    = require('connect')
RedisStore = require('connect-redis')(express)

SessionSockets = require('session.socket.io')

app = module.exports = express()
app.set('port', 3000)
server = app.listen app.get('port')
io = require('socket.io').listen server

cookieParser = express.cookieParser('your secret sauce2')

# Redis as sessioStore
sessionStore = new RedisStore


sessionSockets = new SessionSockets(io, sessionStore, cookieParser)

sessionSockets.on "connection", (err, socket, session) ->

# ..
  socket.on "ping", (data) ->

    # Doesn't work, counter IS NOT saved in redis
    if session.counter
      ++session.counter
    else
      session.counter=1

    console.log '@sess2: '+JSON.stringify session


app.get "/test", (req, res) ->
  body = ""
   # Works, view IS saved in redis
  if req.session.views
    ++req.session.views
  else
    req.session.views = 1
    body += "<p>First time visiting? view this page in several browsers :)</p>"
  res.send body + "<p>viewed <strong>" + req.session.views + "</strong> times.</p>"

The connect.sid session is in redis but "counter" is in memorystore I think

redis 127.0.0.1:6379> get sess:o0wxRV+ykXOIxT3FNwsIG9OX
"{\"cookie\":{\"originalMaxAge\":null,\"expires\":null,\"httpOnly\":true,\"path\":\"/\"}}"
