Hi Huan !

The easiest way I guess would be to not cache the files in the first place.
You can do this with a Meta-Tag:

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

Then of course the next user can still use the back key, since the URI's are
in the global history file. I don't know if you can prevent this. On the
German telekom server the back button is denied by giving each page that is
requested a cookie that is cross-checked. If the time doesn't match the first
request, access is denied.

Hope this helps,
