When I manually update a post / page that page is also not expired and the stale page is served for quite some time – so this whole caching system is quite questionable. Manually blowing away the entire cache or search index when any content was updated was acceptable back in ’98. Now, its completely unacceptable. I’m wondering if anyone has had success with W3 Total Cache and any of the other cache systems (non-cache based) actually working correctly and expiring specific cached content.
