Senthil Kumaran <orsenthil@gmail.com> added the comment: I am not able to understand what you mean by 'endpoint'. Actually, when using tunnels people understand that they often 'tunnel through' the proxy server and here is an example code from the tests which is going to use the set_tunnel method. ph = urllib.request.ProxyHandler(dict(https="proxy.example.com:3128")) o.add_handler(ph) It is the proxy server and port. (Is 3128 called the endpoint of proxy?) Could you please provide some more information on your interpretation and the behavior you observed? ---------- assignee: docs@python -> orsenthil nosy: +orsenthil _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue11448> _______________________________________
