basic-authentication and php?

[Ian Hobson]

Hi all,
I'm trying to set up basic authentication to protect an area of the 
website served by php.

The critical bits of my server directive are.

server (
   listen 80;
   server_name  site.com  www.site.com;
   root /var/www/site.com/htdocs;
   index  index.php index.html index.htm;
   access_log  /var/www/site.com/access.log;
  
   location ~ \.php {
      include /etc/nginx/fastcgi_params;
      fastcgi_pass 127.0.0.1:9000;
   }

   location ^~ /usage/ {
      auth_basic "Hello, Please login";
      auth_basic_user_file /var/www/site.com/passwords;
   }

   location ^~ /ppg/ {
      auth_basic "Hello, Please login";
      auth_basic_user_file /var/www/site.com/passwords;
   }
}

The directory /usage/ does NOT contain any php files and works just fine.

The directory /ppg/ contains index.php - which is sent to the browser, 
not to fastcgi :(

So how can I configure it.  (If basic-auth cannot work, it would be ok 
to use
allow and deny all.)

I'm using nginx 0.6.35

Thanks

Ian
