Which is just another reason why you shouldn't depend on the browser for caching/control-flow. Caching was designed to allow low-bandwidth end-users to take advantage of the fact that static pages don't change. In a struts application, by definition, most pages are dynamically generated. All requests SHOULD be sent back to the server, even those where the user has backtracked. It's up to your application to determine what to do with that backtracking. If you allow it, then you build your application in such a way as to allow a reloaded page to display something meaningful. If you don't allow it, then you provide back a relevent page. Perhaps this is a page that says something like "Don't try to backtrack -- we don't allow/support it" with a link to the last valid page displayed by the user. In any case, it's a server-side responsibility in a dynamic web application to handle backtracking correctly. There's too many variations on browsers out there to let the client handle it, especially when those variations were never originally designed to support dynamic-content pages. Obviously, this is somewhat a matter of "Opinion" and "Preference", but so is using MVC over the so-called Model 1 approach. In my opinion (in the short period of time I've been using Struts), backtracking strategy management isn't easily accomplished in Struts. In WebObjects, there's a page-state-caching mechanism to deal with this kind of problem, and I suspect before I get too far along, I'll end up porting it over in some form to get my production application working under Struts. > A question about your Sony VCR: does it allow you to continue from the places where it get interrupted? Actually, it does.
