Personally, I think very elaborate support for HTTP in httplib, and very
few generalizations and abstractions in urllib* would be the "right"
way to do it, IMO. For example, there might be the notion of an
"http session" object where a single application request can resolve
to multiple http requests (with redirection, authentication negotiation,
cookies, 100 continue, implicit headers, etc).

For compatibility, urllib* can't drop features, and we'd need
contributors who contribute such a refactoring, but IMO that would
be the right way. If applications use urllib *only* for http, and
*only* because it has these multi-request, implicit headers
features, something is wrong with the abstractions.

Martin
