Is there any way to disable resume download in nginx server? I want to stop resume download capability in from URL example.com/media/ but I have no idea how to do that. Also I've searched through internet but I couldn't find anything related to nginx. Is it a server config? Or I should do something else? This is my server config:

# sites-avalaible/default
server {
        listen  80;
        listen  443 ssl;
        server_name     www.example.com example.com;
        ssl_certificate /var/www/example/ssl/ssl.crt;
        ssl_certificate_key     /var/www/example/ssl/ssl.key;
        location /static  {
                alias   /var/www/example/static;
                expires 7d;
                add_header Pragma public;
                add_header Cache-Control "public, must-revalidate, proxy-revalidate";

        }
        location /media  {
                alias  /var/www/example/media;
                # limit download speed after 5mb download
                limit_rate_after 5m;
                limit_rate 120k;
                limit_req zone=lh burst=5 nodelay;
        }
        location / {
                proxy_pass      http://127.0.0.1:8000;
        }
}

I have a media folder on URL example.com/media/ and I want to deny users running scripts in my server. My server app is nginx and in How to deny script execution inside writable directories I couldn't find anything special about specific URL. This is my nginx server config:

# sites-avalaible/default
server {
        listen  80;
        listen  443 ssl;
        server_name     www.example.com example.com;
        ssl_certificate /var/www/example/ssl/ssl.crt;
        ssl_certificate_key     /var/www/example/ssl/ssl.key;
        location /static  {
                alias   /var/www/example/static;
                expires 7d;
                add_header Pragma public;
                add_header Cache-Control "public, must-revalidate, proxy-revalidate";

        }
        location /media  {
                alias  /var/www/example/media;
                # limit download speed after 5mb download
                limit_rate_after 5m;
                limit_rate 120k;
                limit_req zone=lh burst=5 nodelay;
        }
        location / {
                proxy_pass      http://127.0.0.1:8000;
        }
}

I want to deny running any executable stuff in my media URL in which users can upload their files to server. How can I do that? For example when user navigates to example.com/media/bomb.py nginx return 404 error page. I've also changed media folder executing permissions but I need to do it for nginx in order to stop viewing script files.

How can I enable nginx cache for specific URL? I have a django web app and I put my static files such as CSS, JavaScript and ... in a folder called static and I can access them via http://example.com/static/ and I want to config nginx n order to catch these files only from this url. I've read http://www.nginxtips.com/how-to-enable-browser-cache-static-files-on-nginx/ but this option wasn't explained there. I tried below config and restarted my nginx server but I've got errors. This is my sites-available/default config file. What's the problem?

server {
        listen  80;
        listen  443 ssl;
        server_name     www.example.com example.com;
        ssl_certificate /var/www/example/ssl/ssl.crt;
        ssl_certificate_key     /var/www/example/ssl/ssl.key;
        location /static (jpg|jpeg|png|gif|ico|css|js)$ {
                alias   /var/www/example/static;
                expires 3d;
                add_header Pragma public;
                add_header Cache-Control "public, must-revalidate, proxy-revalidate";

        }
        location /media  {
                alias  /var/www/example/media;
        }
        location / {
                proxy_pass      http://127.0.0.1:8000;
        }
}

And this is nginx log file content...

How can I see or even control a client cert traffic in OpenVPN? Is it possible? I'm programming a Client Control Web App and I find nothing about it. Is there any script or commands for that? In OpenVPN Access Server I've seen such thing.

Edit: To be clear I want users traffic usage.

How can I limit a client maximum connection in OpenVPN? What I really want is to restrict more than one device using one client account? How can I do that? Is it even possible? I've seen in OpenVPN Access Server such thing.

I'm developing a website for managing OpenVPN users with Django framework. But I need to know is there any way to extract active users from OpenVPN? My server is running Ubuntu 12.04.
