The chat example works as is.

Because the home page is served from the same origin as the websocket endpoint, the default origin check logic allows the connection to go through.

Edit: OP suggests that the example disable origin checks. It's a bad idea to demonstration a disabled origin check in the examples because disabled origin checks are a security vulnerability in most application scenarios.
