I want to download content from the net - in chunks of x bytes or characters
at a time - so that it doesnt pull the entire content in one shot.
import urllib2
url = "http://python.org/"
handler = urllib2.urlopen(url)
data = handler.read(100)
print """Content :\n%s \n%s \n%s""" % ('=' * 100, data, '=' * 100)
# Disconnect the internet
data = handler.read(100) # I want it to throw an exception because it cant
fetch from the net
print """Content :\n%s \n%s \n%s""" % ('=' * 100, data, '=' * 100) # But
still works !
Apparently, handler = urllib2.urlopen(url) takes the entire data in buffer
and handler.read(100) is just reading from the buffer ?
Is it possible to get content from the net in chunks ? Or do I need to use
HTTPClient/sockets directly ?
Thanks
