The thing is to not only find the correct session, but also the correct
It's required to support the browser-back button where, due to the page
flow, the system awaits to find a JSF state for the page. If you do not
maintain a request id you'll always could have the last JSF state (for
the last page), any browser-back will fail.

MyFaces will store a configureable number of JSF states, say for the
last 20 requests. After then, the browser-back issue is back.
