How do I add YouTube video capability to my proxy?

[Charles Zuck via StackOverflow]

So I created a free proxy using Google's appengine, ( This is the proxy I made: www.websurfer404.appspot.com ) to watch videos at school that are blocked, and the article I read to make this said that the files I added were supposed to have capability to run Flash videos (YouTube videos), but they dont run. It just shows a blank screen. If you guys need me to add files, or show screenshots to help, I'd be more than happy to do so. Also, here is the link to the article I used in making the proxy: http://www.labnol.org/internet/setup-proxy-server/12890/ - Charles
