Hey Theron, Let me take a shot at this for you. I don't claim to be an expert (except when applying for a job ;-) ), so hopefully an expert will correct any mis-information.
Page scope is valid only for a single page. Typically this MAY be the same as request scope. However, if your Action class performs a forward to a different page (or action), page scope will change (because it is a new page), but it is still the same request scope. Request scope changes when the browser makes a request of the server. So a redirect (rather than a forward) will terminate request scope because the browser has to make an additional request to retrieve the desired page. When the user his the back button, NO beans will be used. remember that beans reside on the server (all JSP activities are server side). The beans work with the JSP to generate an HTML document that is delivered to the browser to render. Hitting the back button merely retrieves this previously rendered HTML document from the browser cache; no request is made to the server. Hopes this helps to clarify things for you. And if I have misspoken, I hope that someone will correct me.
