Example: >>> from httplib import HTTP >>> h = HTTP('www.python.org') >>> h.putrequest('GET', '/index.html') >>> h.putheader('Accept', 'text/html') >>> h.putheader('Accept', 'text/plain') >>> h.endheaders() >>> errcode, errmsg, headers = h.getreply() >>> if errcode == 200: ... f = h.getfile() ... print f.read() # Print the raw HTML ... Python Language Home Page [...many more lines...] >>> Note that an HTTP object is used for a single request -- to issue a second request to the same server, you create a new HTTP object. (This is in accordance with the protocol, which uses a new TCP connection for each request.) sHTTP/1.0iPisHTTPcs(dZ)+dddZ7dZ@ddZSdZXdZddZmd Zqd Zd Z d Z RS( s2This class manages a connection to an HTTP server.csC+23d|_4t|_5|o5|i||ndS(sInitialize a new instance.
