Nginx Force HTTPS

Nginx Maps¶

Create a new file on the server with a space-seperated list of old-to-new URLS:
```
/old-url-1 /new-url-1
/old-url-2 /new-url-2
/old-url-3 /new-url-3 
```

Include the map in your Nginx config:

# Place this at the top of your nginx configuration
map $request_uri $new_uri {
    include /path/to/redirects.map; # or any file readable by nginx
}

Make use of the map inside the server block:

# if a redirect is be found in the map file it will use it
server {
    if ($new_uri) {
       return 301 https://$new_uri;
    }
}

You may need to increase map_has_bucket_size within the http block:

http {
    map_hash_bucket_size 256; # see http://nginx.org/en/docs/hash.html
}

Redirect all unmapped requests to their HTTPS equivalent

server {
   if ($scheme = http) {
       return 301 https://$host$request_uri;
   }
}

Add headers to tell browsers they should only use HTTPS

location / {
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

    # re-write redirects to http as to https, example: /home
    proxy_redirect http:// https://;
}

Test the new config with nginx -t and then restart the nginx service
