referencing Global Object in code behind class

[sonny.stevenson]

I created a global object with the following in the global.asax class

<object id="mainObj" runat="server"
class="global_Object.MAIN" scope="Application" />

I have been searching online for a while and I cannot for the life of
me find any resources. How can I reference the global instance
mainObj from any code behind class??

thx,

sonny
