Nope, the problem still appears. AJAX request get cached. And I
finally found the source of it.
In session.inc.php the function call session_cache_limiter('private');
causes to add the Last-Modified header.

I don't know why but on repeated ajax requests, my chrome caches them,
whatever the Last-Modified header value is. Can we change that call to
session_cache_limiter ('nocache');? Or alternatively move up the
$GLOBALS['is_ajax_request'] setting code in common.inc.php to before
session.inc.php gets included and make the session_cache_limiter()
call dependent on whether it is an ajax request.
