Marc,

The way I ususally get round this problem is this:-

Don't worry about the browser cacheing the page. Force the browser to
request the page from the server again by adding a querystring to the end
of the URL which is slightly different each time.

This fools the server into thinking that the browser has requested a
completely new page and therefore the confirmation page is pulled from
the server instead of from the cache

Try something like this:
