I am considering installing wp-cache, but I have a concern. I have a few pages that display RSS feeds. What I would like to know is how does wp-cache know to update the cached page with the new version once that page has been updated? Will my RSS fed pages appear out-of-date for a time or will they update each time the feed updates?
When does wp-cache update? (4 posts)

Posted 5 years ago #You don't have to worry. WP-Cache clears its cache every time you update/publish a post or add/update/delete any of the comments. Basically, anything that would require your feed to be refreshed would also refresh WP-Cache.

RSS feed aggregators are one of two things: PHP or JS. If they are JS, they'll work as normal. If they are PHP, they'll get a shot at executing whenever WP-Cache updates the page (once an hour, once every two hours, whatever). Given most of the aggregators themselves have a time cycle (once every N hours), it is possible that the RSS will have to wait for an extra cache-page-update before it is 'over the time limit' and rechecks the rss feed.

I added "feed" to the "Rejected URLs" list so as not to have any links with feed in 'em cached.
Seems to work.
