Production deployment - nginx & uWSGI

[Glideh]

I've been able to successfully use this great library with my dev server.
Now I'm trying to install a server environment on my local machine (before the true one).
I configured 2 vassals in emperor mode for both my project and its websocket applications.
The one for my project works fine, but I seem to receive only HTTP requests on the websocket one (invalid request block size: 21573 (max 4096))
Here is my websocket vassal:

[uwsgi]

chdir           = /my/project/path
module          = wsgi_websocket
virtualenv      = /my/virtualenv/path

workers         = 2
socket          = /tmp/%n.sock
gevent          = 100
http-websockets = true
vacuum          = true

So my current issue is my websocket receives only invalid request block size: 21573 (max 4096) for each ws: queries
Could somebody help me to debug that ?

Typically this error message appears, if you try to send WSGI instead of HTTP, so probably you misconfigured you nginx.
This is my settings

nginx

    ....
       location /ws/ {
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_pass http://unix:/path/to/web.socket;
        }
    ....

uwsgi

[default]
umask = 002
virtualenv = /web/production/virtualenvs/project
master = true
no-orphans = true
uid = jrief
gid = developer
threads = 1
env = DJANGO_SETTINGS_MODULE=project.settings

[runserver]
ini = :default
socket = django.socket
module = wsgi_django:application
buffer-size = 32768
processes = 4

[wsserver]
ini = :default
http-socket = web.socket
module = wsgi_websocket:application
processes = 2
http-websockets = true
gevent = 1000

Thank you for your answer, my nginx config seems to be the same
(I just copy/pasted it and changed the socket).
I'm going to try a simple copy/paste of your wsgi config.

BTW, which version of NGiNX are you using?

[Glideh]

1.2.6

[jrief]

Please Read The Docs:
"Assure that you use NGiNX version 1.4 or later, since earlier versions have no support for Websockets. "

Oups that was quite simple, sorry.
I saw that but didn't check my version.
Somehow still hoping to have recent pakages from Debian/Ubuntu ...
