@vstinner sorry to bother you, I have a quick question.

the request(...) method is like this:

def request(self, method, url, body=None, headers={}, *,          
            encode_chunked=False):                                
    """Send a complete request to the server."""                  
    self._send_request(method, url, body, headers, encode_chunked)

'request' calls '_send_request' method and '_send_request' calls 'putrequest' inside itself.

So is it good if I encode 'method' parameter to ASCII inside 'putrequest'??!
