If you use response.sendRedirect then you are telling the browser (ie
client) to open the supplied URL.  The browser then makes a new request for
that URL.  So, if your bean is scoped to a request, then it will be out of
scope for the redirect.  If it is scoped for the session or application,
then it will still be there.

On the other hand, if you do a forward operation (pageContext.forward) or an
include, then tomcat handles it all internally, and so it is all one
'request', so a bean scoped as request will be seen by all the pages
included or forwarded to.

Does this clear it up?

Paul

if i use a redirect like an action in a form, it creates a new bean?
