memcached - Expire option doesn't work in Rails.cache -


i use rails.cache.fetch method :expires_in option in rails 2.3.10.

rails.cache.fetch "key", :expires_in => 2.seconds

in development, cache never expired , rails hits cache.

log: "cache hit"

the default cache in rails 2 activesupport::cache::memorystore. not support expiration :expires_in option. in fact, only activesupport::cache::memcachestore has support cache expiration.

in rails 3, :expires_in supported cache stores.
