If a request goes through a 1.0 proxy, the old proxy cannot be expected to
create a Host: header that will eventually reach the origin server.
Therefore I would expect that the Host: header would be just as necessary
when making a request to a proxy.

Now that I've scrutinized this section of the spec, I'm actually quite
surprised the spec doesn't coincide with what I just said.  Do I
misunderstand something?
