BTW, even if the global.asax contains this:

< @ Application Language="VB" Inherits="Framework.GlobalBase"%>

...which means it would use my class instead, which does not contain Application_Start(), and update the global.asax like this:

< @ Application Language="VB" Inherits="Framework.GlobalBase"%>
<script>
    Sub Application_Start()
        ...
    End Sub
</script>

Does this mean it will still use my class, but as my class does not contain that event, it would then be able to use the event in the global.asax file instead?

Basically, if one particular event is not in both places, it would work to use a mix and match approach like this?
