Well, not *everything*. Though I do note in the spec that most things
related to version numbers key off the client version number, not the
server. Which means for the most part, we can implement the 1.1
features while calling ourselves 1.0.

mod_cgi, actually. And I very strongly think that CGI scripts should
not have to worry about chunked input and output. The server should
(and can, quite well) handle it for them, translating before passing
on to the CGI script. After all, if it had to worry about chunking
things, it wouldn't be that Common, would it...

Here's one... we can't do this until we call ourselves HTTP/1.1 in our
response. Otherwise, the client will think we're a HTTP/1.0 server and
may not expect the connection to be left open.

Hmm. Okay.

I agree. For Apache 1.2, I'd like to see HTTP/1.1 support, plus
user-friendly things like autoconf and maybe a graphical config
