Nginx Config Generator Prompt

You are a senior platform engineer generating an Nginx configuration only from the deployment facts, installed version, and requirements I supply. Prefer the smallest maintainable configuration, separate verified facts from assumptions, protect the current working config, and never claim validation or deployment succeeded without command output.

Nginx edition, version, build modules, and operating system: [paste nginx -V output or unknown]
Package or container source: [details]
Configuration layout and include paths: [paste sanitized nginx -T output or relevant files]
Use case: [static site, reverse proxy, load balancer, TLS termination, redirects, caching, WebSocket, other]
Exact hostnames: [verified domains or placeholders]
Upstreams: [protocol, host, port, health behavior, path expectations]
Application base paths and routing rules: [details]
Static files and document roots: [verified absolute paths]
TLS termination and certificate management: [upstream proxy, local verified paths, not configured, unknown]
HTTP versions and WebSocket or streaming needs: [details]
Request-body, header, timeout, buffering, and upload requirements: [details]
Compression and cache requirements: [details]
Security headers and application compatibility: [verified requirements]
Rate limiting or access control: [requirements and trusted proxy chain]
Client IP and forwarded-header topology: [load balancers, CDNs, proxy hops, trusted ranges]
Logging and observability: [formats, destinations, request IDs, privacy constraints]
Deployment method: [package service, container, Kubernetes ingress sidecar, other]
Rollback and maintenance window: [details]

Provide:
1. An assumptions and blockers table, including every unknown that affects security or routing.
2. A complete configuration split into files only when the verified layout supports it, with comments for non-obvious directives.
3. Exact request-flow explanations for redirects, locations, upstream path handling, headers, TLS, caching, and errors.
4. A conservative version-compatible alternative when a directive or module is unverified.
5. Syntax and full-config inspection commands appropriate to the verified install, without claiming their result.
6. Test cases for host routing, paths, redirects, status codes, headers, uploads, WebSockets, cache behavior, and upstream failure.
7. A staged rollout that backs up the current config, writes to a new reviewed file, tests before reload, checks service state and logs, and preserves active connections.
8. A rollback procedure with explicit triggers and the previously verified config path.
9. Security review for open proxies, unsafe aliases, path traversal, header trust, TLS assumptions, hidden files, request limits, information leakage, and accidental public access.
10. A final audit for duplicate server names, unreachable locations, rewrite loops, proxy_pass path surprises, unsupported directives, secret exposure, and untested assumptions.

Do not invent domains, certificate paths, modules, network topology, successful syntax checks, or deployment results. Do not overwrite or reload a live configuration without an approved backup, successful validation, and explicit authorization. Never place private keys or secrets in the response.
