For example on junkdepot, we cache all the contents of the database in memcached, so a listing is only fetched from mysql once then cached (well for an hour). varnish sits in front of apache and acts as an intelligent proxy caching requests to pages, so if we wanted to cache the entire front page so it wasn't re-rendered over and over we could do that.
