Trying to test out Turbo:StreamsChannel

[epugh]

I am trying to verify that TurboStreams works... I'm having luck when I go direct to Rails from web browser, but with HAProxy having issues.

I wanted to test out connectivity using acli but always get a rejection:

 ./acli -u http://localhost:3000/cable -c Turbo::StreamsChannel
Connected to Action Cable at ws://localhost:3000/cable
Subscription rejected

I'm guessing something about signatures. Anyway to avoid this?
