Reverse Proxy

Mode Detection

• Repo mode — templates in tooling/network/. Scaffold or modify proxy configs.
• Chat mode — user pastes config or error. Diagnose and provide corrected config.

Nginx

Test and reload config (never restart)

nginx -t                        # test config syntax
nginx -s reload                 # reload without downtime
systemctl reload nginx          # alternative

Basic reverse proxy config

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
