should you handle session data in a controller or a model for an MVC framework?
===

I am working within an MVC framework (specifically, PHP's CodeIgniter). I am trying to follow "best practices" as much as possible, but I don't have much experience with MVC in the past. Is it bad practice for me to retrieve data from a session within the Controller? Should I "ask" the model if, say, a particular session value is 'foo' or 'bar', or should I do that directly inside the Controller? I'm thinking I should do it inside the Model since the session data is technically data, but I just want to make sure. Just to be clear, I don't store the session data in the database at all, so I'm not running a query.
