Do cached feeds get cleared after each new post? Or does it depend on certain plugin settings.
I'm asking this because I'm working on a plugin that does a dynamic Google News sitemap as a feed. I'd like to make sure the news sitemap is always cleared after a new post independant of any plugin settings or single/multi-site situation.
If that is not possible, I suppose I can always prevent caching at the filter_request level with
define( 'DONOTCACHEPAGE', 1 );
Or am I mistaken?
