Restrict access to folder using APACHE

Hello,

I’m using APACHE on a Windows 2000 machine. I just finished a catalog application using PHP/MySQL. I didnt create a user/password script. Only one person will do the editing on the catalog. I know there’s a way to restrict access to a folder by using APACHE and prompt the user for a user/password.

I already read on two of the books I have and I don’t get specific information. Can you please tell me how to do it?

Thanks in advance,

Leonel
