Would RequestDispatcher's forward method work for you?  I like it because 
it keeps the request object intact (as well as the session and anything 
attached to it) during the hand-off, but the down-side is that you can't 
pre-alter the request's contents (i.e. the HTTP parameters) without 
extending the class (can somebody tell me why the base class doesn't have 
those setters?!).  This is easy with sendRedirect because you can load the 
URL with your parameters ("/blah.jsp?option1=a&option2=b") but you're more 
limited with forward(String).  Something to consider...
