Personally I am probably -1 on overloading util.redirect() to do  
this. That function
isn't too complicated, but probably should be kept just for the  
simple cases. If
someone knows enough to use other cases, they are probably knowledgeable
enough to know how to do it properly themselves at the lower level.
