Unfortunately, you won't be able to use request scope for this. The
reason is that, in a JSP 1.1 environment, <bean:include> has to internally
do a separate request in order to buffer the output. Because it is a
separate request, request scope attributes are not shared.
Once we can migrate to Servlet 2.3 / JSP 1.2, it will be possible to
implement <bean:include> so that is shares the same request.
