Turbogears with gevent-socketio: request Key Error - turbogears2

Question

I try to use gevent.socketio with my TurboGears 2 Website:
in the ini-file i use
[server:main]
use = egg:gevent-socketio#paster
transports = xhr-multipart, xhr-polling, websocket
host = 0.0.0.0
port = 8080
when i try to access the controller in the Webbrowser:
#expose('wago.templates.test')
def index(self):
socketio_manage(request.environ, {"/stat": StatNamespace}, request=request)
return dict()
i get the following error:
Traceback (most recent call last):

KeyError: 'socketio'
I used several tutorials for pyramid to introduce myself to gevent-socketio.
I tried it with older versions from TurboGears2, gevent and gevent-socketio, i also tried this module but always the same error.
i'm pretty new to sockets, so maybe i'm just missing something obvious

Answer 1

the gevent-socketio recognizes socket requests only from a specific url (socket.io/1/)
because TurboGears uses the python function names as url it is not posible to us "." or "1" on the regular way. A simple solution:
#expose()
def _default(self, *args):
args = list(args)
if "socketio" in request.environ:
#do socketio stuff...
else:
abort(404)
