The time_expire can be set to 0 to force a cache refresh and to None to prevent the content from ever expiring. You can clear one or more cache variables with cache.ram.clear(regex='...') does this apply to gae memcache? if memcache decorates some controller, and I know its key, how can I force recache its new result?
