        session['user'] = scope['query_string'].decode()
        status, headers = 307, [(b"location", b"/")]

    # Read a stored info from the session
    user = (session.get('user') or 'anonymous').title().encode()

    await send({"type": "http.response.start", "status": status, "headers": headers})
    await send({"type": "http.response.body", "body": b"Hello %s" % user})

app = SessionMiddleware(my_app, secret_key="sessions-secret")

# http GET / -> Hello Anonymous
