It''s just the custom class I created that''s being cached. Any ideas

Sorry if this is a complete newbish question, but I''m trying to wrap my head around creating custom classes in my rails webapp. I''m normally a Java developer, but I figured I''d give RoR a try and see how I like it, and whether it would be useful for production use with a new client.
