sorry,that not work for me,because my socket domain run on differrent with socket caller and my socket is http.
I'm not good at English.

[Aaron Belovsky]

in your client code (socket caller), make sure you've specified that your client will only communicate over a web socket transport.

socket = io.connect(socketUri, { transports: ['websocket'] });

[Aaron Belovsky]

Cannot use http — must use the websocket transport so that your connection does not have to upgrade from http to websocket.

my socket is on heroku cloud,can you tell me to upgrade http to socket.

Download the sample project: https://github.com/ambelovsky/gosf-sample-app

. ./scripts/getdeps.sh
. ./scripts/run.sh

Modify scaffolding.html on line 15:
var socketUri = 'ws://localhost:9990';

Replace "localhost" with your Heroku server IP address.
