Create Nginx Reverse Proxy Configuration

Create a production-ready Nginx reverse proxy configuration for [APPLICATION_NAME] with the following specifications:

Requirements

• Application name: [APPLICATION_NAME]
• Domain name: [DOMAIN_NAME]
• Backend servers: [SERVER_1:PORT], [SERVER_2:PORT], [SERVER_3:PORT]
• Load balancing algorithm: [round-robin/least_conn/ip_hash]
• SSL certificate path: [CERT_PATH]
• Static files location: [STATIC_FILES_PATH]
• API endpoints: [/api/, /graphql, /ws]
• Caching requirements: [YES/NO]
• Rate limiting: [REQUESTS_PER_SECOND] requests/second
• WebSocket support: [YES/NO]
• Max body size: [SIZE]MB

Deliverables

Generate complete Nginx configuration including:

Main server block for HTTP (port 80):

• Listen directive with server_name [DOMAIN_NAME]
• Redirect all HTTP traffic to HTTPS (301)

HTTPS server block (port 443):

• SSL/TLS configuration with HTTP/2
• SSL certificate and key paths
• Strong cipher suites (TLSv1.2, TLSv1.3)
• Security headers (HSTS, X-Frame-Options, etc.)

Upstream configuration for [BACKEND_SERVERS]:

• Upstream block named "backend"
• Load balancing with [ALGORITHM]
• Server definitions for all [BACKEND_SERVERS]
• Health check parameters
• Keepalive connections

Proxy configuration for all locations:

• Proxy headers (Host, X-Real-IP, X-Forwarded-For, X-Forwarded-Proto)
• WebSocket support headers if [WEBSOCKET_SUPPORT]
• Proxy timeouts and buffer settings
• Client max body size [MAX_BODY_SIZE]

API routing for [API_ENDPOINTS]:

• Location blocks for each API path
• proxy_pass to backend upstream
• Rate limiting zone configuration
• CORS headers if needed

Static file serving if [STATIC_FILES_PATH]:

• Root directive pointing to [STATIC_FILES_PATH]
• try_files for SPA routing
• Long-term caching for assets (images, fonts, CSS, JS)
• Gzip compression configuration

Caching configuration if needed:

• proxy_cache_path definition
• Cache zone configuration
• Cache validity rules
• Cache control headers
• Stale cache serving on errors

Rate limiting:

• limit_req_zone definition
• Apply [REQUESTS_PER_SECOND] limit to API routes
• Burst configuration
• Rate limit error handling

Security and performance:

• Gzip compression for text content
• Client body buffer size optimization
• Connection timeouts
• Log format and access logs

Output complete nginx.conf ready for production deployment.
