hash_cache a bogus function that never worked?

I never used this, but I am wondering that maybe it only works in
production environment instead of development and test envs?

hash_cache is not intended as a response caching mechanism. Rails has
a number of solutions for this such as page, action, and fragment
caching. There is a nice peepcode video on caching in rails, btw, and
a number of other resources available.

In answer to the rails environment question, hash_cache doesn't work
in development for the reason stated: the classes are reloaded, wiping
out the class variable holding the cache. Similarly, normal caching in
rails is turned off in the development environment as well.

~/myrailsapp $ cd config/environments
~/myrailsapp/config/environments $ diff development.rb production.rb
