Curiously enough, IE usually does this in my experience. Something like the
below causes everything but IE5 to reliably reload the page. Even with
"Reload every time" set IE5 does not always reload content, including one
memorable occasion where it was showing the last generated HTML instead of
the 500 server error some buggy mod_perl code was getting despite multiple
reloads.
