Thanks for the great plugin.
I have a slightly off-topic question, but I saw your post about memcached on wordpress.org.
I using the object cache -> memcached replacement files from http://dev.wp-plugins.org/browser/memcached/trunk and I’m not sure how to set the memcached cache to expire. I’ve tried adding an expiry in wp-config but that isn’t working.
Do you know how to reset the expiry time of the cache? I’ve got memcached working via a slave server but nothing I try works to expire the cache.
