Thanks Johan,
I was a little big unclear. By default the HTML pages returned from wicket has
no-cache, so the back button usually posts request to server. When the previous
page url is RedirectPageRequestTarget, the page instance is found in page map
and rendered again. Why is the Page.onRedirect() method final? If this method
is not final, I can override it, check internal state and decide to call
setResponsePage(some other page).
Sample:
To create an order, user has to go through several pages of order build wizard.
On the final page he submits the order. At this time the order is removed from
session. When the user presses "Back", the previous page cannot render, because
there is no order, user has to start at the first page of the wizard.

When a user presses "Back" in a browser the page doesn't render again at least
not in the serverside. By default it is a puur client side thing. (you can
configure
the page in configureResponse to always go back to the server when a user
hits back)
So what gets throwed at what time?

Hi,
I have a not bookmarkable page (page with a form), when user clicks a link
("submit"), the model data are cleared and confirmation page is displayed.
Now, when the user pressed "Back" in browser, the page renders again, but
because the model changed, it throws.
I want to be able to detect, when the old page is again requested and
redirect user to another page. But I don't know how the handle it, I suppose
that calling setResponsePage during rendering phase is too late.
Another solution is to remove the page from page map, but it is not nice,
because the user will see error page.
Thank you, Jan
