Sorry, above assertion is mistaken. Hunchentoot returns T for boolean
in all cases whenever auth-res exists in the GET parameters
list. Therefore, it's not possible to make a distinction between a NIL
(which means false) boolean parameter that is supplied and a parameter
that isn't even supplied. (Please correct me if I'm wrong.)
