I'd start by saying "move to Squid-2.7" before thinking about HTTP/1.1
if you wanted to stay in the -2 train.

The big thing is to sort out some kind of flow control so 1xx responses
were handled. There's very limited communication between the client and
server side at the moment.

Chunked encoding needs to be properly supported for both client and server
side stuff, for requests and replies.

That'd be a good starting point. Henrik understands what needs to happen
quite a bit better than I do. But a lot of the stuff to make HTTP/1.1
happen involves some code reorganisation and none of us have the time
to do that; and noone bar me is going to end up doing it to a Squid-2
tree on our own dime..
