Yes, it's because of the response.setDateHeader("Expires",0); This indicates
to the browser when the data on the page is to be considered stale, and the
0 sets the header to be very, very stale (Jan 1, 1970 I think). Your
browser is informing you that the page has expired and letting you know that
in order to get an "updated" version it has to resubmit the form data, which
could cause problems on some sites.
