Nginx & Reverse Proxy Toolkit

Generate battle-tested Nginx configurations for any deployment scenario. Covers reverse proxy setup with proper headers, SSL/TLS with Let's Encrypt automation, load balancing across multiple backends (round-robin, least-conn, IP hash), rate limiting for API protection, WebSocket proxying, static file serving with cache headers, gRPC proxy, proxy-level response caching, security hardening, zero-downtime deployments, IP access control, geo-blocking, multi-domain setups, and performance tuning. Includes complete copy-paste configuration templates, debugging commands, and a troubleshooting guide for common errors (502, 504, 413, redirect loops, SSL failures). Every config follows production best practices: HTTPS by default, conservative timeouts, security headers, and test-before-reload workflow.
