so user can't use back/forward button to view the page after they leave the
page. For example, my page1 will be a login page, page2 will be some
choice listing, page3 will be some confidential info page, and if user
leave page3 with/without logoff and go to some other pages or sites, the
next user can use back/forward key to see the previous user's confidential
info. How can I prevent this to happen? Any good idea on how to implement
this?

well, if the page is generated by a servlet, you can use
setHeader("Expires","-1"), which instructs the browser not to cache the
page. If the page is static HTML, I don't know how to set the header, so
you'll have to look to an HTML guide.
Hope this helps
