Servlets, send redirect and request scope

In a typical (MVC1) application. You have a HTML-FORM posting to
servlet-A and getting request parameters/values from the request
object.

HTML-FORM ==> Servlet-A

If I have to put a redirect in between the form and A. The request
values are lost. Is there a generic way to restore those request
values. I could put all the keys/values in a session object and then
recollect the values in the servlet. But, I wish there was a generic
way that possibly avoided using the session object.

HTML-FORM ==> response?.sendRedirect ==> Servlet-A

Something like response.putRequestValue...
