Need help with - http auth

Here is solution for Nginx with PHP-FPM

Code: [Select]

location /subfilder/ {
       index index.php;
       auth_basic "Unauthorized";
       auth_basic_user_file /home/user/.dashauth;
}

But it doesn't work right with Apache + Nginx Reverse Proxy login works, but it offers to download php file...

I'm missing something
