Things to watch out !!!!

How socket io works

web socket vs socket.io

Everytime page RELOADS new socket session gets created disconecting the old. Mongo DB collections get created based on socket session id for each user, so if page realoads you collection will change based on your new session and old collection being unaffected anymore.
