Redirect Maps with NGINX

install | source | nginx | advanced | analyze | php | redirect

Basics first

unconditional redirect that keeps the requested path

            location / {
                    # taking over some FQDN at once
                    return 301 https://pub.nethence.com$request_uri;
            }

same but for the whole URL but the url scheme

        return 301 https://$host$request_uri;

redirect all 404

    # define error page
    error_page 404 = @notfound;

    # error page location redirect 301
    location @notfound {
        return 301 /;
    }

Whole folder

NOT IDEAL - getting rid of .html extention from the URL

            rewrite ^(/.+)\.html$ $1 permanent;

NOT IDEAL - permanent redirect, renaming folder /service/ to /server/

            rewrite ^/service/(.+) /server/$1 permanent;

MUCH BETTER - a true 301

            location ~ ^/server/(.*) {
                    return 301 /daemons/$1;
            }

Without a dedicated vhost conf

also when you’re migrating a whole web site to another sub-domain, you can eventually pack it within the default_server stanza as such

            if ($host = doc.nethence.com) {
                    return 301 https://pub.nethence.com$request_uri;
            }

            return 301 https://pub.nethence.com/;
