clearing user's browser history

[Anon]

I've written a login screen for a user
to enter password and id and then I
verify it through my php code and
then if correct forward them to their
directory and their index.htm page.

What I'm trying to do is to clear the
user's history so someone else can't
access it.

Can someone tell me if their is a
php function that will clear the
user's history or if not, what I
should do.

Thanks.

php cant do this..i think no external code could..except the broswer itsself.
one suggestion would be to set a session cookie for the user. you can then get their index page to check to see if the session is current and redirect to login page if not. it won't stop a snooper finding the page in the history but should stop them viewing the contents.
