3. Nginx Configuration

Current Status: ✅ PROPERLY CONFIGURED

File: frontend/nginx.conf

SEO Routing (NEW)

# SEO files - proxy to backend for dynamic generation
location = /robots.txt {
    proxy_pass http://backend:8080;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_cache_bypass $http_cache_control;
    add_header Cache-Control "public, max-age=3600";
}

location = /sitemap.xml {
    proxy_pass http://backend:8080;
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_cache_bypass $http_cache_control;
    add_header Cache-Control "public, max-age=3600";
}

Benefits

• ✅ Proper proxy headers (Host, X-Real-IP, X-Forwarded-For)
• ✅ Protocol forwarding (X-Forwarded-Proto) for correct HTTPS detection
• ✅ Cache bypass support
