Websockets in Flask
In regular HTTP requests the connections between client and server are short-lived, a client connects to the server, sends a request, receives the response and then closes the connection. In this model the server can serve a large number of clients using a small number of workers. The concurrency model in this situation is typically … Read more
Why is PyMongo 3 giving ServerSelectionTimeoutError?
We’re investigating this problem, tracked in PYTHON-961. You may be able to work around the issue by passing connect=False when creating instances of MongoClient. That defers background connection until the first database operation is attempted, avoiding what I suspect is a race condition between spin up of MongoClient’s monitor thread and multiprocess forking.
Are a WSGI server and HTTP server required to serve a Flask app?
When you “run Flask” you are actually running Werkzeug’s development WSGI server, and passing your Flask app as the WSGI callable. The development server is not intended for use in production.

nginx + uwsgi: — unavailable modifier requested: 0 —
Original answer For Python 2 on Ubuntu 11.10, using upstart, install the python plugin for uWSGI with apt-get install uwsgi-plugin-python and if you’re using an ini file to configure your uWSGI app, then add plugins = python to the [uwsgi] section and it should solve this problem.

WSGI vs uWSGi with Nginx [closed]
Ok, guys this confusion is because of lack of detail from several sources, and the naming of these protocols, and what WSGI actually is. Summary: WSGI and uwsgi both ARE protocols, not servers.

Nginx serve static file and got 403 forbidden
