# current code:
unless @users = cache_get("active_users")
  @users = User.all(:active => true)
  cache_set("active_users", @users)
  # object caching can be used to avoid pulling huge amounts of data
  # from the database.
  # you could have calle cache_set with an expiration time as well:
  # cache_set("active_users", @users, 10)
