Does anyone know how I reset the cache for the minifeed and updated stories? 

I have a problem with added Authors (this works) to a story, not showing until Applicationpool is recycled or site restarted. 

I've tried;

CacheHandler.Instance.RemoveCachedObject(story.CacheKey);
CacheHandler.Instance.RemoveCachedObject(feed.CacheKey);
CacheHandler.Instance.RemoveCachedObject(actor.CacheKey);

and

CacheHandler.Instance.RemoveCachedObject(story);
CacheHandler.Instance.RemoveCachedObject(feed);
CacheHandler.Instance.RemoveCachedObject(actor);

The functions work, the problem is that the updated story won't show until site is restarted.  :-/
