Hmm ... the manual page for httplib reminds us that it is used by urllib,
and although it does implement the HTTP client-side protocol it's actually
much easier to use urllib. Here's a snippet form a crawler program I wrote
some time ago (warning: not tested under 2.0) which shows that it's very
easy to use urllib to read HTML pages from a server:
ignored = 
distance = 1
while distance < MAXDIST:
for URL in l[distance-1]:
if URL == '-':
f = sys.stdin
f = urllib.urlopen(URL)
data = f.read()
if f is not sys.stdin:
p = myHTMLParser(fmt, URL)
links, rubbish = p.close()

Bottom line: use urllib, that's what it's for. Easier, too! Good luck.
