How to use the geventhttpclient.URL function in geventhttpclient

def get(path="/sub/channel"):
    url = URL("http://%s/%s" % (os.getenv("HTTP_HOST", 'localhost'), path))
    http = HTTPClient.from_url(url)
    response = http.get(path)
    return response

if __name__ == "__main__":

    N = 1000
    C = 10

    url = URL('http://127.0.0.1/index.html')
    qs = url.request_uri

    def run(client):
        response = client.get(qs)
        response.read()
        assert response.status_code == 200


    client = HTTPClient.from_url(url, concurrency=C)
    group = gevent.pool.Pool(size=C)

    now = time.time()
    for _ in xrange(N):
        group.spawn(run, client)
    group.join()
