Please don't hand carve an http client. You'll be lucky to get 0.9
conformance with any reasonable amount of work, and if you want
something that works correctly with 1.1, well, I'll see you next year.

Also note that http/1.1 prohibits more than 2 concurrent connections to
a single hostname:port combination, and that is only allowed so that you
can use one connection for interactive (small) requests and one to
pipeline the bulk of the data through.
