Sweepy allows you to expire file-based cache (page cache and fragment cache) on Rails on multiple boxes. If you don’t want or don’t need to setup memcached, and just want to simply use Rails page and / or fragment caching, sweepy automatically handles page expiration. Sweepy scales well - Sweepy uses UDP broadcasts for cache cleaning. This way you can add as many machines as you want, and cache expiration times will remain the same. » sweepy on github
