it would be nice if $c->res->redirect returned a 303 appropriately if  
$c->req->method eq 'POST'.

i have in the past trapped it in 'end' to fix up the $c->res->status  
if == 302 and $c->req->method eq 'POST', but lately i just don't bother.

You should be able to set the http status code with ->redirect(302) if I'm reading the source code correctly.
