The WSGI PEP doesn't specify any WSGI specific exceptions.
- The sample CGI example that the PEP provides also raises an AssertionError for this scenario:

Also note that Paste's HTTP server (Paster) and CherryPy both raise AssertionErrors for this scenario:
- Paste: https://bitbucket.org/ianb/paste/src/4f5cfde87603/paste/httpserver.py#cl-166
- CherryPy: http://www.cherrypy.org/browser/trunk/py2/cherrypy/wsgiserver/__init__.py#L2...
Can you clarify what you meant by a WSGI-specific exception type?
I was thinking we would derive a custom exception type, e.g.: class WSGIException(Exception): pass and then raise instances of it. I didn't know that the other servers were raising AssertionError, which still seems like the wrong thing to raise at runtime in a production environment: I guess we can follow their lead in this case.
