Deny directly access to javascript files

Hi all.

I'd like to deny directly access to my js files, but I'm in trouble.

Imagine I have a web site www.example.com an it uses js files, so, someone tries to accesswww.example.com/scripts/script.js and it opens the source code of my script on the browser. 

I'd like to deny this type of access.

I've already tried to put a web.config in the script folder as follows:

<configuration>
   <system.webServer>
      <security>
         <authorization>
            <removeusers="*"roles=""verbs=""/>
            <addaccessType="Allow"users=""roles="Administrators"/>
         </authorization>
      </security>
   </system.webServer>
</configuration>

It works in part, it denies access to my js file, but my web application gets denied, too and stops work.

I need just block directly access, could you give me a help?

thanks,

Daniel Costa
