Nginx – How to we restrict dynamically nginx upload/download speed per user

bandwidth-controlnginxPHP

It's possible to restrict the speed using the rate limit on a specific location.

However, how can we do it dynamically ?

Let say you have paid vs non-paid users and you want to give an higher bandwidth to paid users.

We would need to dynamically check in the Database and allow a certain speed for this particular group of users.

Do you have any nginx module in mind ?

Yes, you can rate limit on a specific location.

location /something/ { 
    set $limit_rate  4k; 
}

You can also surround the limite_rate with statements like if as well to dynamically control the rates. See this link for further details on limite rate: http://wiki.nginx.org/NginxHttpCoreModule#limit_rate

There is another module you should be mindful of: http://wiki.nginx.org/NginxHttpLimitZoneModule

That module allows you to set limits of connection count. So, even if you set a low limit, if they can just make 10 connections, your limit is rather meaningless.

I suggest you have private and public users get different links so that nginx can easily distinguish between the types of users and verify in your application layer for security.

Correct way in new versions of nginx

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}
