Hello, I have nginx as reverse proxy to server with IIS. The server  
have files .cvs. When trying to download any file the server asks for my  
username / password but if you put the correct data always reapplies the  
user and password and can not download the file. Their configuration is  
very basic i have hope to improve it little by little.

any suggestions to solve the problem?  
Thanks.

the sites-enabled/default file is:

server {  
listen 80;  
server\_name [www.xxxxxxxx.com](http://www.xxxxxxxx.com);

```
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
            root /var/www/nginx-default;
    }

         location / {
            proxy_pass http://Dir.to.IIS.server;
            include /etc/nginx/conf.d/proxy.conf;
            index index.html index.htm;
    }

```

}

The proxy.conf:

proxy\_redirect off;  
proxy\_set\_header Host $host;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
client\_max\_body\_size 10m;  
client\_body\_buffer\_size 128k;  
proxy\_connect\_timeout 90;  
proxy\_send\_timeout 90;  
proxy\_read\_timeout 90;  
proxy\_buffer\_size 16k;  
proxy\_buffers 32 16k;  
proxy\_busy\_buffers\_size 64k;

the nginx.conf file:

user www-data;  
worker\_processes 1;

error\_log /var/log/nginx/error.log;  
pid /var/run/nginx.pid;

events {  
worker\_connections 1024;  
}

http {  
include /etc/nginx/mime.types;  
default\_type application/octet-stream;

```
access_log /var/log/nginx/access.log;

sendfile on;

keepalive_timeout 65;
tcp_nodelay on;

gzip on;

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

```

}
