When handling a CONNECT request, the response will have no body.  In 
mod_proxy, the CONNECT handler currently skips most filters and writes via 
the connection filters.  However there is a block of "#if 0" code which 
intends to send only a FLUSH bucket down the filter chain.

That's not quite the case of an entirely empty brigade, but it seems close 
enough to warrant highlighting.
