 * 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   Will my RSS fed pages appear out-of-date for a time or will they update each 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?

 * 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.

 * You can worry, but it won’t do you much good… 😉
 * 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.
