I'd like to touch base again regarding a couple of features that are keeping us from using WP Super Cache on a multisite installation:
1) When a post or page is updated, I believe that this refreshes the cache on the entire installation. (Correct me if I'm wrong.) With many users updating content often, we worry that this would put too much of a burden on the server. So instead, it would be better if the plugin only refreshed the cache for the particular blog that has been updated, as the Quick Cache plugin does.
2) When a theme is updated (or certain other things happen), the cache is not automatically updated. Therefore, sub-site blog owners will not be able to begin using their newly activated themes until the cache expires. It would be great if the cache would be updated for the particular blog on a theme change (again, as Quick Cache does), or if sub-site admins had a "Clear Cache" button of their own to force a refresh if it's ever necessary.
Is there any chance of this functionality being added to WP Super Cache soon? That would make it much more effective for multisite use.
Thanks for listening!
