This is also something I'd stick in a module. It sounds like it belongs in a User class, for example, and the user class could know to cache this value. With Catalyst, you can also do caching in the controller, and for the project I'm working on, I just moved some caching out of a Mason component, into the controller. This worked well. > 4.

This _definitely_ belongs in controller code, and even before I started using Catalyst I was trying to move this stuff out of Mason components, using MasonX::WebApp. -dave /*=================================================== VegGuide.Org www.BookIRead.com Your guide to all that's veg.
