difference between ...

[David Hajoglou]

Would there ever be any difference between the output of the following:

(looking on the mod_perl quick reference card)

>From Apache::URI
        $str = $uri->query()


>From Request object
        $str = $r->args();

As far as what they hold about the request, would these ever differ, or
do they access the same data (in different ways)?


Thanks 
David
