What I would like to have is a mapping between a custom file extension to a class that is not System.Web.UI.Page but a class of mine that inherits from System.Web.UI.Page.
i.e.:
*.aspx -> System.Web.UI.Page *.my -> My.Package.MyClass (inherits from System.Web.UI.Page)
I know I can map any extension to be treated like .aspx but I can't find the way to do what I have in mind.
Thanks d
