Persisting Notes Session across multiple servlet requests

We are working on servlets which use Notes Session extensively. For performance I would want to persist a single Notes Session across multiple incoming requests.

Is this preferred and recommended. Most thread posts have been of the view that NotesThread.sinitThread should be used before using any Domino Objects in a request and NotesThread.stermThread after the request.

Please Advise and comment.
