Not as far as I can tell... I think maybe this problem is part of the
CGI concept as well; since it uses environment vars to pass on
selected headers, there's a risk that custom headers overwrite env
vars that the shell depends upon. Unless you jump through hoops to
escape them, etc, or encode all headers into one long string, somehow.
But then it's no longer CGI per se.

Me neither, I'm just guessing my way ahead :)

We could potentially derive from one of the requesthandlers and
implement our own, but then we'd have to figure out a good way to get
all the request data from the web server to the handler script,
essentially reinventing CGI. Unless we want to do it all in one
mega-script, in-process.

Oh well...
