Request & Response#

Similar to other frameworks, Falcon employs the inversion of control (IoC) pattern to coordinate with app methods in order to respond to HTTP requests. Resource responders, middleware methods, hooks, etc. receive a reference to the request and response objects that represent the current in-flight HTTP request. The app can use these objects to inspect the incoming HTTP request, and to manipulate the outgoing HTTP response.

Falcon uses different types to represent HTTP requests and responses for WSGI (falcon.App) vs. ASGI (falcon.asgi.App). However, the two interfaces are designed to be as similar as possible to minimize confusion and to facilitate porting.
