HTACCESS Password protecting a specific URL

I am using .htaccess to rewrite URL's, so the url for

 www.mypages.com/home 

would map to

 www.mypages.com/index.php?page=home 

I have the url

 www.mypages.com/secure 

that I wish to protect using standard .htaccess password protection, is there anyway I can secure just this page?

Thanks in advance

John
