Question

nginx 1.19.9

I have URLs like this

• https://example.com/men?mindbox-message-key=...
• https://example.com/women?mindbox-message-key=...
• https://example.com/chile?mindbox-message-key=...

and I need to block some IP. How do I do this?

server {
    ...

    location /my-custom-url {
        if ($args ~* "mindbox-message-key") {
            deny all;
        }
    }

    ...
}
