Better how?  urlopen actually works when the Content-Length
header is provided.  If it doesn't, it's a bug in Python.
Can you or can you not provide an instance of a URL which
does not provide a Content-Length header using your above
code when IE in fact appears to get the length?

By the way, the above code works perfectly well when applied
to the first URL you gave above.  Have you got one where
it doesn't?
