Fix www to Non-www Redirect for Your Discourse Forum

To add a redirect from the "www" subdomain to the non-www version of your domain in Discourse, you'll need to modify your web server configuration. Here's how you can do this:

server {
    listen 80;
    server_name www.yourdomain.com;
    return 301 $scheme://yourdomain.com$request_uri;
}

server {
    listen 80;
    server_name yourdomain.com;

    # Your existing Discourse configuration goes here
    # ...
}

This Nginx configuration will handle the redirect from www to non-www for your Discourse installation. Here's a breakdown of what it does:

1. The first server block listens on port 80 for requests to www.yourdomain.com.

2. It then uses a 301 (permanent) redirect to send these requests to the non-www version of your domain.

3. The second server block is where your existing Discourse configuration should go.

To implement this:

1. Replace yourdomain.com with your actual domain name in both places.

2. Add this configuration to your Nginx configuration file (usually located at /etc/nginx/nginx.conf or in a separate file in /etc/nginx/sites-available/).

3. If you're using HTTPS (which is recommended), make sure to also set up similar redirects for port 443.

4. After making changes, test your Nginx configuration with nginx -t.

5. If the test passes, restart Nginx to apply the changes: sudo service nginx restart or sudo systemctl restart nginx.

Remember to also update your DNS settings to ensure that both the www and non-www versions of your domain point to your server.

Would you like me to explain any part of this configuration in more detail?
