I'm just testing uWSGI by following the quick-start guide in official web site. But, I am facing a problem.
This is what I did. It's exactly same as the steps in quick guide.
$ uwsgi --http :9090 --wsgi-file foobar.py

And this is my foobar.py:
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return [b"Hello World"]
After this I tried to connect to the http://localhost:9090 in this way.
curl -v 127.0.0.1:9090
These are the responses.
curl -v 127.0.0.1:9090

I expected Hello World but I get empty messages from the server.
How can I solve this?
