Size of a remote URL

[Justin]

Ok so the problem is that my code is not requesting the headers
properly.  I get back.  Just that.  I don't know what the difference is
between the IE request and mine

My code:
for y in linklisttype:
w = urlopen(y)
z = w.info()
x = z.getheader("Content-Length")
file_sizes.append(x)
Is there a better method for getting headers than urlopen?
