That Old Cache
Getting sick of memcached just kicking your stuff out of memory in Rails? Maybe you've thought "Gee, wouldn't it be nice to just serve the old cache while I refresh it." Well, look no further! That Old Cache is a Rubygem that does just that, giving you the ability to fire off a process to refresh the cache once it expires, without the annoying "initial load" problem that affects your users.
