Nonsense.

Bullshit.

Again with the invalid snippets of code, eh?  You're trying
awfully hard to avoid getting helped.

WTH is "y"?

Those look like correct results to me.

I'll tell you _one_more_time_:  use Ethereal.  Here's the
transaction for your first URL:

  GET /~harnad/temp/ariadne-rae.doc HTTP/1.0
  Host: www.ecs.soton.ac.uk
  User-agent: Python-urllib/1.15

THERE IS NO CONTENT-LENGTH HEADER.  What do you expect urllib
to do?  The second of your URLs is also a 404 error with no
Content-length header.  The third URL is valid and does return
a content-length header:

  GET /systech/techsupport/procedures/2kcleanup.doc HTTP/1.0
  Host: www-admn.csun.edu
  User-agent: Python-urllib/1.15

  HTTP/1.1 200 OK
