>Has anyone figured out to get the Page Expiration thing to work? I have problems when users are allowed to update data, then push the back button and go back to previous data states, which don't jive with saved data. I would like users to get a Page Expiration notice when they try to go backwards, but since this is the web, I have no way of how they got to a page, by legitimate means or otherwise.

The Java code to remove a page from history is:

< SCRIPT LANGUAGE="JavaScript">
self.location.replace('PageToGoTo.htm’) ;
< / SCRIPT>

This will replace the current page they are on in the history with the page they need to go to. Thus a Back would not get them back to the data page.
