What am I doing wrong?

Are you sure that sdf.lonestar.org:80 supports websocket at all?

I tested this site with websocket.org’s demo, and it was quite obvious that the site does not support websocket – unexpected status code returned from the site.

Thanks for the update.  I incorrectly assumed that if a webserver supported HTTP 1.1 it would support WebSockets.
Is there an known host that you know of that does support WebSockets?

I assume ws is normal and wss is secure.

Cool - it kind of works.  I have to setup secure sockets though.
