Yes, I agree caching and expiring caches can get pretty complicated fast ... what you have is good enough for me now. Thanks for the clarification.

It is a very simple in-memory cache that persists with the FacebookSession object. This actually varies depending on the way that you use the plugin. If you are making a Canvas app, you have a new session on every request. If you are making an iframe or external app, then that session is persisted in session[:rfacebook_session], and you can nil that out when it is not needed anymore. In the future, I would like to make the caching smarter, but I think that a real caching solution should be implemented on an app-by-app basis. There really isn't a magic bullet for such things.

I've just started to play with it. I have a question on caching - how long does the cache last? Is there a way to expire it explicity or set a TTL? Raghu Srinivasan Thanks for RFacebook.
