Yes, and it's been discussed here quite a bit. Search for 'cache' or 'expired' and you will probably find several discussions.
In short if the last page was the result of a POST request and it isn't cached in the browser, the browser will warn you that requesting the page again (which is needed if the page isn't cached) will result in the for being posted to the server again.
Most people solve this be redirecting to a page after a form submission. This causes the last page to be the result of a GET request, not a POST request.
