an internal redirect is within the context of a single request; apache 
hasnt closed the original connection or anything.  If you want to see a 
cookie you just set, its still there in the response headers you set 
up...just pull it out again !

but i guess you are looking to see that the browser successfully 
accepted the cookie by seeing if it comes back again.  in that case you 
have to use an external redirect of some kind, yes.
