I accidentally replied to earlier to David only instead of the list.  As I
said earlier, this is the result of dumping the request object whilst running
under Apache -- my intended production environment. 

BTW, you may see some non-Dancer cookie stuff in there; that is because I'm
porting my authentication scheme from the old cgi setup in stages.  I don't
think it is necessarily causally related to the emptiness because POSTed
params don't work at all right now.
