WSGI Protocol Linter
====================
This module provides a middleware that performs sanity checks on the
behavior of the WSGI server and application. It checks that the
:pep:`3333` WSGI spec is properly implemented. It also warns on some
common HTTP errors such as non-empty responses for 304 status codes.

't LintMiddlewarec B sD e Z d Z d � Z d � Z d � Z d � Z d � Z d � Z RS( s� Warns about common errors in the WSGI and HTTP behavior of the
server and wrapped application. Some of the issues it check are:
- invalid status codes
- non-bytestrings sent to the WSGI server
- strings returned from the WSGI application
- non-empty conditional responses
- unquoted etags
- relative URLs in the Location header
- unsafe calls to wsgi.input
- unclosed iterators
Error information is emitted using the :mod:`warnings` module.
:param app: The WSGI application to wrap.
