Nginx Remove WWW And Respond To Both
According to https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/#server-name-if, you should use:
server { server_name www.example.com; return 301 $scheme://example.com$request_uri;}server { server_name example.com; # [...]}
I believe it's better to add two seperate server blocks to avoid unnecessary checking by the if block. I also use the $scheme variable so that HTTPS requests will not be redirected to their insecure counterparts.
server { listen 80; server_name www.mydomain.io; rewrite ^ $scheme://mydomain.io$uri permanent;}server { listen 80; server_name mydomain.io; # your normal server block definitions here}
Another way to code it :
if ($http_host ~* "^www\.(.+)$"){ rewrite ^(.*)$ http://%1$request_uri redirect;}It works even with multiple domain names on the same code.
