Yesterday I started playing with basic caching for PriceChirp and tried what I thought would be easy. Boy was I wrong. It turns out what I was attempting to do is not supported by :memory_store in the development environment. Before moving to :mem_cache_store, I was able to find a work around. The work around is outlined below for those who do not have the option of using memcached. However, if you can use memcached, it is by far the better route to take.

My goal was to cut down on the number of database hit by caching the resultant ActiveRecord object in :memory_store.
