EMBEDDING A MINI WEBSITE ON A FACEBOOK PAGE

I have built a mini flash website and would like it installed on faceebook. I tried to create an app using heroku which i have done, problem is app does not show my mini website embedded instead it just shows the app [login to view URL] where that app is, is where my mini web site should be. I have uploaded all files to my servers the guys who host my website. So i think maybe i am not perfect when it comes to embedding mini websites within a facebook page. The mini website should ideally be in a canvas page within my facebook page link above and not a stand alone page as it is now where my app is displayed. Need this urgently done thanks. look forward to correspondence from you many thanks
