Hello @nolancrestfield
Thank you for reaching out and I am happy to help!
You can manage the Maximum lifetime of cache objects in Performance>Page Cache>Advanced section of the plugin.
Once the content for the post or page is update, the W3 Total Cache will purge the cache for that specific page and all pages associated to serve the update version.
You an manage this in Performance>Page Cache>Purge policy section of the plugin. There you canspecify the pages and feeds to purge when posts are created, edited, or comments posted
Thanks!
Hello @nolancrestfield
JUst to add to this, we do have a Always Cached extension in Performance Extensions. It prevents page/post updates from clearing corresponding cache entries and instead add them to a queue that can be manually cleared or scheduled to clear via cron
