To criticize code that's already giving satisfaction
is nearly beyond me.  I'll point out, though, that
the original questioner might consider this alterna-
tive which has, I believe, evident advantages for
long-term maintenance:
  from urllib import urlopen

  URL = "http://www.uic.edu"
  page = urlopen(URL).read()
  print page
Note that urllib is one of the batteries the standard
Python distribution includes.

My summary:  use higher-order facilities when applicable.
