Now that I think about it, that's a confusing way to say "either
ISO-8859-1 or US-ASCII".

I'll write something and send it around by Monday night.

Somehow we have to manage the upgrade of HTTP/1.0 to HTTP/1.1 for
existing CGI programs. HTTP/1.1 places a number of new requirements on
responses in order to be compliant. Either the CGI programs will have
to themselves be upgraded and vetted, or else the servers have to
parse the output and validate it if they're going to be labelled
HTTP/1.1. I think this is a general requirement for protocol upgrades
when a gateway is involved.

This is an issue for any kind of plugin/API/CGI web server, isn't it?
