asynchronous programming. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written to use Tornado’s own interfaces (such as which do every- thing they are going to do before returning). There are many styles of asynchronous interfaces: • Callback argument • Return a placeholder (Future, Promise, Deferred) • Deliver to a queue removed. 5.3.2 tornado.httpclient — Asynchronous HTTP client Blocking and non-blocking HTTP client interfaces. This module defines a common interface shared by two implementations, simple_httpclient and curl_httpclient

RuleRouter and ReversibleRuleRouter are implementations of Router and ReversibleRouter interfaces and can be used for creating rule-based routing configurations. Rules are instances of Rule class

There are many styles of asynchronous interfaces: Callback argument Return a placeholder (Future, Promise, Deferred) Deliver to a queue Callback simply raise an exception (as opposed to the ad-hoc error handling common in callback-oriented interfaces), and Futures lend themselves well to use with coroutines. Coroutines will be discussed in depth class.
