I'm trying to understand when I should manually purge pages, and have some questions: 1. Will the cache be purged for a published Wordpress post or page anytime I update the post/page? Or must I manually purge the post? 2. When publishing a new post, the front page and blog pages both automatically link to the post. Will the cache of the front page and blog pages automatically get reset as soon as a new post is published? Just wondering if posting a new or updating an old post/page automatically triggers an immediate cache reset? Thanks!
