"page parameters retained"?
The parameters of which page? The one you are going back to?
"browser back button is not to be used"?
The browser has a back button whether you like it or not. Users may not see
if you hide it but still press "ALT-LEFT" while cursing over you.
The back button can be available through link:
ExternalLink backLink = new ExternalLink("backLink",
"javascript:history.go(-1)");
add(backLink);
The semantics of the back button is like "undo". This is not always exactly
what you want, e.g. a webshop where the shopping cart must be kept in the
session so that when you go back the things in your cart does not disappear.
