Subject: How to restrict Directory access in httpd

Hi ,

    I am running apache(2.2.29) static libraries into my application . I want to restrict access to particular directories from where my application is running. So for example:

 My application is  at D:\new_user\<application directories>  and i have some private files at D:\private_file

Then user if provides path like ../../private_file via web interface to my web-app , then he is able to access this "private_file" in my server.

How can I restrict it ?? How to restict in a way only D:\new_user\<application directories>\* is accessible to web-interface?

Thanks ,

Ishan
