adding www to my domain at nginx server

Look at here:

According to this link the solution is:

server {  
    server_name  domain1.com;  
    rewrite ^(.*) http://www.domain1.com$1 permanent;  
}  

server {  
        listen 80 default_server;  
        listen [::]:80 default_server ipv6only=on;  

        root /home/user/www/domain1;  
        index index.php index.html index.htm;  

        server_name www.domain1.com;  

        include hhvm.conf;  

} 

Oh, wait. Do you mean you really want a redirect, such that if a visitor types in ‘domain.com’, they will be redirected to ‘www.domain.com’? My response doesn’t help with that, it only enables the server to handle the ‘www’ form (or both forms, depending on which version you use).

Thanks @matt. <br> <br>I’ve already added www to my DNS. <br> <br>if I added www to the domain in the etc/nginx/sites-available/mydomain, not at nginx.conf in the nginx root folder. <br> <br>That works, but counted as an extra request. so an empty page takes 2 requests, which is a bad practice. <br> <br>I believe there a way how to do that, but not sure yet how!! <br> <br>regards
