Redis client is not configured correctly for session store

[glkn]

Derby store is correctly configured with redis settings with

var redisClient;
  if (process.env.REDIS_HOST) {
    redisClient = redis.createClient(process.env.REDIS_PORT, process.env.REDIS_HOST);
    redisClient.auth(process.env.REDIS_PASSWORD);
  } else if (process.env.OPENREDIS_URL) {
    var redisUrl = parseUrl(process.env.OPENREDIS_URL);
    redisClient = redis.createClient(redisUrl.port, redisUrl.hostname);
    redisClient.auth(redisUrl.auth.split(":")[1]);
  } else {
    redisClient = redis.createClient();
  }

Yet session store uses different code

store: new RedisStore({
        host: process.env.REDIS_HOST || "localhost",
        port: process.env.REDIS_PORT || 6379
    })

hence app fails to start when using non-default settings for redis.

I think RedisStore should be initialized like this?

var session = require('express-session');
var RedisStore = require('connect-redis')(session);
