You don't have to refresh the page, you could make it so that your next page click loads the full page instead of using ajax/pjax.
quick pjax e.g.:
<html data-lastupdated="1234567890"...
$.getJSON('/lastupdated.json', function(lastupdated) {
if(lastupdated > $('html').data('lastupdated'))
{
$('a[data-pjax]').removeAttr('data-pjax');
}
});
