It is not legal to maintain a reference to a request after that request
has been completed.
My advice is to look at your problem completely differently -- plan on
pulling out of any request whatever you need to save, and save *that* data
as session attributes. Trying to save the requests themselves will lead
you to design an application full of spaghetti code, because you'll try to
make everything look like a servlet that processes requests.
It would also be worth your time investigating how Model-View-Controller
(MVC) application frameworks like Struts
<http://jakarta.apache.org/struts> encourage you to architect web
applications.
