[imp] IE Problem with history (security)

[Ian Roberts]

I have a problem with ie on windows ox (haven't experienced the problem with other browsers) where someone logs in and reads the emails.  THEN when logged out, or after reboot, another user with no mail account can gain access to the read emails by beginning to write the URL of the webmail and they will get a list of links with random numbers and if you choose one of these you can gain access to that whether its an email or something.

How can this be prevented?

Thanks in advance,
Ian
