Hi,
So it seems to me now that offloading websocket handling to the offload
thread is the way to go,
but I still have my original problem, how
to uwsgi.websocket_send('message') to the right websocket?
Also I would need to have a loop somewhere to constantly check for new
messages, I thought using a timer but I can't have values <1. Can I use the
offload threads for this too?
Thanks
Avraham
