I would like to know how to find the web site page that a video is hosted on from a video cache link and how to do it.

Code:
http://cache15.stormap.sapo.pt/dld/fbbb3691dcf90b3be9198f2e7d88cb24/5165ffd5/vidstore14/videos/dc/98/3d/5135274_2cu6p.mp4
I know the video is hosted on sapo.com but I don't know how to find the exact web site page. I want to use a video but would like to use their player and give them the proper credit for their file and not just hotlink it.



Is this possible? Thanks for any help.
