Hi Zach!

No, at the moment you can't.  CONTENT-STREAM is not documented because
it's of no use once the request object has been created.  I think the
best way to implement this would be to add a new slot (something like
"RAW-POST-DATA") to the request object and only fill it if some
special variable which usually is NIL has a true value.  What do you
think?

If you want to work on this the meat of it should be around line 110
in request.lisp and you should also decide if you want to do the same
thing for multipart/form-data POST requests.

I can also do this but probably not this week - I'm pretty busy.  So,
clean patches including documentation are preferred... :)

Cheers,
Edi.
