Thanks, this seems to work properly for both the IIP (index.php) and the IIP sidebar (pals/sidebarpal.php).

For the benefit of others reading this:
The only restriction is that the forced update interval (600 seconds, in extremebikini's post) should not exceed the cache update interval for any individual pal. Otherwise, that pal would update on each page refresh that occurred between its cache update interval and the forced update interval.
