How are inputs blocked?

[Graxeon]

I have some scripts that I don't want others to use...but how can I make it so people cannot use my files to link on their websites?

 

 

 

Here is an example page (only one that I could find with the feature, lol) :

 

This: http://www.anilinkz.com/bleach/bleach-episode-195/

Calls this: http://www.anilinkz.com/files/getflv.php?url=http://www.veoh.com/videos/v166668182TfK55Sy

 

But when you go to this (I changed the Veoh URL) : http://www.anilinkz.com/files/getflv.php?url=http://www.veoh.com/videos/v16981216Bs8Q4y9s

 

It doesn't work (my guess is because the "getflv.php" has a code in it which has a list of allowed URLs and it doesn't link to anything else).

 

Why? How? And can you show me how to do this for my files?
