Essentially it comes from the httplib code, which examines the URL, breaks
it up into various components, and does not find a host component. This is
why I wondered whether you had missed a slash out: "http/hostname" raises
that exact exception.

I would suggest you use urllib to read the URLs. The httplib is mostly
support code for that library.
