Public bug reported:

In nova/wsgi.py, there is a function but the return value is limited to
None, which can also be a response.

    def process_request(self, req):
        """Called on each request.
        If this returns None, the next application down the stack will be
        executed. If it returns a response then that response will be returned
        and execution will stop here.
        """
        return None

>From thte comments we can see, the return value for this function should
be "None" or response.


Thanks,
Jeffrey Guan
