Answer 1

Hmm,
I don't think so, with URL re-writing. The reason is because application2 would need to do the re-writing, and so would need to know the JSESSIONID of session1, which presumably it wouldn't know.
Options, I guess, would be to pass the JSESSIONID for session1 to application2, which stores it, then uses it to re-write the URL when coming back to application1. Or you could add a persistant cookie that stores the JSESSIONID from session1, then when you enter into application one, check for the cookie, and re-use the same session. You would want to double check your session timeout however, because the session may die if the user is in application2 for too long.
