Dear Joseph,
Thanks a lot for your informative mail. In fact, it has set me off on a few
more queries!

Does it hold for <jsp:include> also?

'Sorry, I'm not clear on this! Does it have to be the same servlet context?
In my case, JSP pages are used where, say, AccProducts and Location beans
are used. That generates 2 different servlets, right? So, this scope'll be
available for both these, is it?
