Support for other files extension

Hi

I have a client who wants to run .js file under mod_suphp because some 
files after processing doesn't get the right permission owner.

For .php file, I have it working with mod_suphp but when I'm trying the 
same thing for .js extension, nothing seems to be working.

logfile=/var/log/suphp.log

Is it a support feature or I'm totally wrong about it ?

Thank you !
