Hi
You need to set a token that is unique for the request.
The Action class has methods to do this for you
protected boolean isTokenValid(HttpServletRequest p0)
protected void resetToken(HttpServletRequest p0)
protected void saveToken(HttpServletRequest p0)
I thnk saveToken plants the token in the request and in your form
automatically, they can be checked to be still the same when the form is
submitted. If not your form is out of sync with your expected flow of events
Then in your action , check it's valid and set a new value afterwards
if (dispatch.compareTo(DELETE) == 0) {
if (!isTokenValid(request)) {
errors.add(ActionErrors.GLOBAL_ERROR,new
ActionError("error.transaction.token"));
nextURL="error";
} else {
// do the right thing here
nextURL = "continue";
}
} // end if valid token
if (!errors.empty())
saveErrors(request, errors);
saveToken(request);
return (mapping.findForward(nextURL));
:-)

Subject: Page Expiration
How can I make it so that when the user clicks on the
back button, he is presented with an error stating
that the page has expired (does this make sense?)
