In 1.3 we started setting the Expires Header on resource pages to work
around some aggrresive caching settings some browsers are on.
In some cases you should get the 'The page cannot be displayed
_because the page has exired from cache and in order to get it again,
I'd have to send the post parameters again_ Do you want me to do
As opposed to the 'the page cannot be displayed' because it sent a
404 error message.
