Viewed by a logged in user, ie. the same case when we check page_touched. Also note we are checking against a local cache. The way it's updated is unspecified :) > Also, checking on every page view is out of the questions for external sites, > right? So we'd still need a push interface for these... I think they'd use a cache with a configured ttl. So they wouldn't actually be fetching it on each view, only every X hours. _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
