Background: ASP has an Application[] collection that is shared across  
sessions.

How do you do that in RoR?

I need a mutex to read/write this as I need to share a hash across  
sessions.

Thanks in advance, Pete

You can use Rails.cache facility that is now available as part of the  
Rails 2.1 release. Ryan B.’ screencast at  
[#115 Caching in Rails 2.1 - RailsCasts](http://railscasts.com/episodes/115-caching-in-rails-2-1) is an  
excellent overview
