Recently I was working on a project that required an Nginx server to redirect all traffic to https://domain.com, and by all traffic I mean anything that did not start with https://domain.com needed to be rewritten to that. This included:

  • http://www.domain.com and http://domain.com
  • https://www.domain.com

To do this, the configuation file on Nginx should look like this:

      server {
            listen 80;
            server_name domain.com www.domain.com;
            return 301 https://domain.com$request_uri;
      }
      server {
            listen 443 ssl;
            ssl on;
            ssl_certificate /path/to/your.crt;
            ssl_certificate_key /path/to/your.key;
      
            server_name www.domain.com;
            return 301 https://domain.com$request_uri;
      }
      server {
            listen 443 ssl;
            ssl on;
            ssl_certificate /path/to/your.crt;
            ssl_certificate_key /path/to/your.key;
            server_name domain.com;
      }

Note that you can switch around the settings for the two two 443 blocks and instead force it to write to www; I’m a fan of excluding it.
