Redirects in nginx are really powerful, here are some cool and common examples.

all domains http > https and remove www

Redirect all http traffic which has no other better matching server_name defined from www.domain.tld and domain.tld to https://domain.tld

# redirect http://www to https non www                                                                               
# global and maybe not the best in all setups
server {
   listen 80;
   server_name ~^(www\.)(?<domain>.+)$;
   return 301 https://$domain$request_uri;
}

http > https

Redirect all of the incoming http requests to https for selected domains

server {
        listen 80;
        server_name domain.tld www.domain.tld;
        return 301 https://$host$request_uri;
}

http > https with exceptions

Redirect all or a part of the incoming http requests to https, you can use this the other way round to redirect a small part of the traffic to https and localion / to the normal backend.

server {
    listen 80;
    server_name domain.tld *.domain.tld;

    # Excluded location from https redirect
    # I use this for lets encrypt validation
    location ~ acme-challenge {
        root        /etc/letsencrypt/temp;
    }

    location / {
        return 301 https://$host$request_uri;
    }
}

More will be added ;-)

If you have a redirect you just can't get to work, leave a comment so I can give it a try.
