refreshed when a special event is triggered.
Refreshing by triggers is pretty complicated. You usually have news in
your front-end templates (perhaps even more than one), but the news items
are usually changed on the admin side, so clearing of cache can't be done
in normal template processing - something would have to keep track of all
possible templates that may have cached that news item.
That way you could keep the latest news on your website in cache until
they have been updated.
You can have cache refreshed immediately when news updates by using:
<div phptal:cache="100d per php:news.id . news.last_updated_date">
(this means that separate cache copy will be kept for every version of
every news)
Caching based on last updated date (or version) handles that easily, and
the only downside is that it leaves some outdated cache files behind, but
it's not very hard to clean them up:
