- :param sock: Server socket, must be already bound to a port and listening.
- :param site: WSGI application function.
- :param log: File-like object that logs should be written to.
- If not specified, sys.stderr is used.
- :param environ: Additional parameters that go into the environ dictionary of every request.
- :param max_size: Maximum number of client connections opened at any time by this server.
- :param max_http_version: Set to "HTTP/1.0" to make the server pretend it only supports HTTP 1.0.
- This can help with applications or clients that don't behave properly using HTTP 1.1.
- :param protocol: Protocol class. Deprecated.
- :param server_event: Used to collect the Server object. Deprecated.
- :param minimum_chunk_size: Minimum size in bytes for http chunks. This can be used to improve
- performance of applications which yield many small strings, though
- using it technically violates the WSGI spec. This can be overridden
- on a per request basis by setting environ['eventlet.minimum_write_chunk_size'].
- :param log_x_forwarded_for: If True (the default), logs the contents of the x-forwarded-for
- header in addition to the actual client ip address in the 'client_ip' field of the
- log line.
- :param custom_pool: A custom GreenPool instance which is used to spawn client green threads.
- If this is supplied, max_size is ignored.
- :param keepalive: If set to False, disables keepalives on the server; all connections will be
- closed after serving one request.
- :param log_output: A Boolean indicating if the server will log data or not.
- :param log_format: A python format string that is used as the template to generate log lines.
- The following values can be formatted into it: client_ip, date_time, request_line,
- status_code, body_length, wall_seconds. The default is a good example of how to
- use it.
- :param url_length_limit: A maximum allowed length of the request url. If exceeded, 414 error
- is returned.
- :param debug: True if the server should send exception tracebacks to the clients on 500 errors.
- If False, the server will respond with empty bodies.
- :param socket_timeout: Timeout for client connections' socket operations. Default None means
- wait forever.
- :param capitalize_response_headers: Normalize response headers' names to Foo-Bar.
- Default is True.
