There is no way to retroactively expire Web pages. Most sites (including banking sites) ask users to close the browser window after logging out.
You may be tempted to set the Expires header in all pages so that they expire immediately, but I do not recommend this, because it breaks the back button functionality, by forcing resubmission whenever you revisit a page in your browser history. This can cause warning dialogs for pages received as a result of POST requests and can also unintentionally cause certain operations to be repeated.

I am wondering how do I logout a user completely and make sure the pages/data aren't visible?
when user logouts out, i issue auth.logout()
i am using ssl/https.
i try it now, i logout.. but, when i hit the back button, i see the prior page.
though, clicking anything will require me to login of course.
i want to "expire" the pages after the user logs out.
