url shortner with fb like button

Please who can help me to find a script. (short url)
to go to the url you must click on a fb like button

elaborate pls.

I think he wants a content locker which makes the Visitor click Share to visit a url from his website.

O goody, a guessing game! Ok, lets have a try here. If I read another post from the OP I would say he is blackhatting on FB. So, if I had to guess, I would say he wants people to click his FB like button before they can go to the URL they came for. If they don't like him, they don't get the link. I don't know if it is even possible to do that other than a clickjacking script but I think I will score high in the guessing game.
