wsgiref — WSGI Utilities and Reference Implementation¶

New in version 2.5.

The Web Server Gateway Interface (WSGI) is a standard interface between web
server software and web applications written in Python. Having a standard
interface makes it easy to use an application that supports WSGI with a number
of different web servers.

Only authors of web servers and programming frameworks need to know every detail
and corner case of the WSGI design. You don’t need to understand every detail
of WSGI just to install a WSGI application or to write a web application using
an existing framework.

wsgiref is a reference implementation of the WSGI specification that can
be used to add WSGI support to a web server or framework. It provides utilities
for manipulating WSGI environment variables and response headers, base classes
for implementing WSGI servers, a demo HTTP server that serves WSGI applications,
and a validation tool that checks WSGI servers and applications for conformance
to the WSGI specification (PEP 333).

See http://www.wsgi.org for more information about WSGI, and links to tutorials
and other resources.
