Question

I am using nginx on Rackspace cloud following a tutorial and having searched the net and so far can\'t get this sorted.

I want www.mysite.com to go to mysite.com as

Answer 1

try this

    if ($host !~* ^www\.){
        rewrite ^(.*)$ https://www.yoursite.com$1;
    }

Other way: Nginx no-www to www

server {
  listen       80;
  server_name  yoursite.com;
  root /path/;
  index index.php;
  return       301 https://www.yoursite.com$request_uri;
}

and www to no-www

server {
  listen       80;
  server_name  www.yoursite.com;
  root /path/;
  index index.php;
  return       301 https://yoursite.com$request_uri;
}
