No, it only works with plain old html files.
If you want to show an asp page the way I would do it is just put a normal Html content feature on the page then in the editor go to source view and put in an iframe linking to your asp page <iframe src="/urltoyourasppage.asp" width="100% height="800px" />
Its not a perfect solution to get it sized right but it will work.
Hope it helps,
Joe
