if node cluster used, i'm getting response: cannot /user. without cluster, able service https.get("/user").

also, using cluster, check if redis, http(s), socket.io , express module should declare in workers part or declare globally?

the httpsapp.get() nested within socket space because want reply specific socket. there way around structure?

anyone figure our why httpsapp.get() not servicing request? , declaration appropriate? thank you!
