When even THAT doesn't work (sigh), then you'll have to make sure the URL is actually
different each time. Place a bogus parameter at the end of it each time. I usually
do something like
http://foo.com/servlet/bar?count=1
And then increment the value assigned to "count" every time the page is served. Ugly,
but it fools even the stupidest browsers.
