it is not a problem david.
example, you open a page which required you to login (with a username and
password) prior to opening that page. then let's say, after that, you logged
out and closed your browser...
then someone comes snooping into your computer and found the URL in the
history. when he clicks on it, he gets the expiration page warning. isn't
that better than letting him read what should have been a private page for
you? it might have been your email.
the warning page simply states that the page cannot be opened unless you
have to log in again from another page. it's a security measure.
| Warning: Page has Expired The page you requested was

| To resubmit your information and view this Web page, click
