I just tested it with leaving the header, all ajax requests responses are as they should be. So we can safely remove the header_remove(). Oddly enough, adding the charset utf-8 header a line lower broke all jquery get requests. The success handler is not being called anymore.

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.
