Accessing Session variable from class

[LyncSype]

I start in a page that inherits from System.Web.UI.Page. Page.Session is not null at this point. The page creates a new class. This class inherits from another class that inherits from System.Web.UI.UserControl. Once I get into the class, Session is null. What do I need for Session state to carry into the class?Both the page and class are in the same webapp.
