can you update this to work with the latest wpmu:
http://quentin.unblog.fr/wordpress-mu-wpmu/wpmu-caching/wpmu-object-cache-using-apc/

it gives me this error:
Warning: Cannot modify header information – headers already sent by (output started at /website/wordpress-mu/wp-content/object-cache.php:184) in /website/wordpress-mu/wp-content/plugins/wp-super-cache/wp-cache-phase2.php on line 48

tnx
