How to configure multiple static directories in nginx?

To configure multiple static directories, you need to use multiple location directives in the nginx configuration file. Here is an example:

server {
    listen 80;
    server_name example.com;
    root /var/www;

    location / {
        index index.html;
    }

    location /static1 {
        alias /path/to/static1;
        expires 7d;
    }

    location /static2 {
        alias /path/to/static2;
        expires 7d;
    }
}

In the mentioned configuration, /static1 and /static2 are two different URL paths that correspond to the static file directories /path/to/static1 and /path/to/static2. Both of these static file directories will be served by the nginx server and will have the Expires field in the response headers set to 7 days.

Please note that when using the alias directive to specify a static file directory, the trailing slash / at the end of the path is required. Otherwise, Nginx will append the requested URL path after the path.
