I'm using httplib to grab bunch of resources from a website and i want it at minimum cost, so i set 'Connection: keep-alive' HTTP header on my requests but i'm not sure it actually uses the same TCP connection for as many requests as the webserver allows. i = 0 while 1: i += 1 print i con = httplib.HTTPConnection("myweb.com") con.request("GET", "/x.css",

问题 conn = httplib.HTTPConnection("www.encodable.com/uploaddemo/") conn.request("POST", path, chunk, headers) Above is the site "www.encodable.com/uploaddemo/" where I want to upload an image.
