[hybi] Support for sub-protocols on the WebSocket API?

[Clebert Suconic <[e-mail]>]

I was looking for a way to send a custom opcode on a subprotocol, but
the WebSocket API (at least the one I found in most browsers) only
provides three very basic methods for sending, and nothing where I
would be able to use on  sub-protocol specifics as defined on the
spec. I could only find ways to send payload from client to server.

Is there any other API where I could make use and still use it to
develop sub-protocols in javascript?

I was looking into defining a subprotocol in javascript and be able to
use it on any client where web-socket is supported.



Thanks,
