local network or from the same machine. This generally would refer to requests
forwarded from an upstream proxy. Also see the above FAQ for what a fast

Applications that expect long request/response times and/or slow clients.
Gunicorn use Eventlet or Gevent to manage concurrency.
How might I test a proxy configuration?
Check out slowloris for a script that will generate significant slow

should be comfortable that all is well with your configuration.
