Manual talk:$wgCacheEpoch

How does this work? If the default value is in the past, does that mean that the wiki sees the cache as being "old", and therefore expires the page?
 * No. Only pages that are cached before the date value are expired. If the value is in the past, the cache created after the date will be kept untouched. --Superxain (talk) 05:09, 18 August 2012 (UTC)
