Thanks igor, that really clarifies a lot of things..a couple of followup question though..
So as you said versioning is implemented to handle the back button (and subsequently "forward" properly, but i wonder if wicket enforces a hit to the server on a browser back button by setting every response header as no-cache/no-store (or by setting the page expiry etc)..otherwise wouldnt it be the browser cache showing the last viewed page, instead of wicket showing the page from the session (or the serialized version of the same if an older page).. Also when you say just the page objects with their component graph are stored, i assume also the models associated with the components are also stored (thats where detach comes into play)...right ?
