[erlang-questions] Push a message to cowboy websockets

[AD]

Barco,

 Looks you got it by just in case my websocket_info looks like

websocket_info(Info, Req, State) ->
    io:format("cowboy: got a websocket message ~p~n",[Info]),
    case Info of
        {_PID,?WSKey,Msg} ->
                {reply, {text, Msg}, Req, State, hibernate};
       ........
       ........

And then in my gen_servers to send a message to all clients i just do

gproc:send({p, l, ?WSKey}, {self(), ?WSKey, Msg})

Hope that helps.

-AD
