http every 25 seconds

[ashwin31]

I ran the django example and everything is working good except that I am seeing http GEt and POST requests every 25 seconds.

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
The WebSocket transport is not available, you must install a WebSocket server that is compatible with your async mode to enable it. See the documentation for details. (further occurrences of this error will be logged with level INFO)

I looks like socketio is in longpoling mode because the local server is not supporting webscoket. Am I correct?

Please do not write issues on this package when you just have a question. The issues board is for actual bugs. Use the discussion board when you have a question or need to ask for confirmation that you have found a bug. Thank you.

The problem that you have is actually not a problem, the output of your Django app clearly indicates what's hapnneing:

The WebSocket transport is not available, you must install a WebSocket server that is compatible with your async mode to enable it. See the documentation for details.

Hi @miguelgrinberg sorry for that. I will keep that in mind.

If it is possible, can you tell me how to enable websocket support on python manage.py runserver ?

[miguelgrinberg]

My understanding is that the Django dev web server cannot support WebSocket. I'm not super familiar with this server, but back when I evaluated it I could not find a way to make it work. I suggest you use Gunicorn, which has good support and you have the choice to use it with threads, eventlet or gevent.

Thank you.
