Because there is no body in a HEAD request.  What is useful are the
Content-Type, Content-Length, and etag headers.

Is r.getcode() == 200?  That indicates a successful response; you
*always* much check the response code before interpreting the response.

Also I'm pretty sure that "HTTP 1.0" is wrong.
