about JSP inclusion file, request scope and session scope

[esolve]

let's say there are two jsp files, main.jsp file and included.jsp

main.jspa has: <jsp:include page="/WEB-INF/includes/included.jsp" />

I have two questions:

1) my understanding is: the local variables(property) in main.jsp can't be seen in included.jsp, so can local variables in included.jsp be seen in main.jsp?

2) if I set the scope as "request" in main.jsp <jsp:useBean id="requestBean" class="coreservlets.BakedBean" scope="request" />, it seems that the variables(property) can be seen in the included.jsp? does this mean if there is no indication of scope, the default scope is "page"?



3) there are two different operation: redirect and forward
My understanding is: with forwarding, it is the same request, so the request scope is valid. with redirection it is different request, so the request scope is invalid
then how about session scope? does redirection means another session or the session scope is still valid?

thanks
