How to make an anti-leech system?

[Guest_imported]

Hi,
I have a domain name (

http://www.sicarmy.org)

wich is under apahe webserver and I want to do something that I've already tryed but I wasn't able to pull it off.

What I want is some kind of anti-leeching protection to all my files and all my folders. I have files of the following types: .gif .jpg .swf .php .htm .zip .mp3 etc and if some direct links to any of the files with this extensions (and others) inside the root folder or in any other sub directory like:

http://www.sicarmy.org/file.zip

or

http://www.sicarmy.org/mp3/music.mp3

or

http://www.sicarmy.org/downloads.html

or

http://www.sicarmy.org/downloads/covers.html

and so on, if people go directly to do this I want it to simply block it and this files would only work if people go into

http://www.sicarmy.org

or just

http://www.sicarmy.org

(not just sicarmy.org) and then they follow the links to see what they want to see or to download what they want.

I think that this is made within the .htaccess file and i've already tryed many ways and used many examples across the web but it didn't work any of it, please help.

Thanks a lot.

take a look at this site

there is a detailed description how to do that

or search the web for "direct linking" or "bandwidth theft"

hope that helps
