What is happening?
Your browser first looks, when opening a page, if there are cookies for it,
if yes then he uses that cookie.
(that is much quicker then uploading the page)
old cookie => old page
Refresh the page should refresh only the page bur also the cookie !
So for uploading "new" page after refresh your browser will use that new cookie to give the "new" page quickly.
But in your case the cookie is not refreshed. Old Cookie => old page.
that can only mean that in your browser (or in windows) the refresh rate (time) is to high (slow), you must set that to a shorter time.
and then not only refresh page will work, but you should get correct page direct without refresh needed.
