1. Purpose and Educational Scope

HTTPLens is an open technical reference library and client-side diagnostic suite created to assist software developers, API architects, DevOps engineers, and system administrators in understanding HTTP standards (RFC 9110, RFC 9111, RFC 9457), CORS mechanics, and header configurations.

2. Permitted Use & Code Snippets License

All code examples, configuration templates (Nginx, Apache, Caddy, Cloudflare Workers, Express.js, FastAPI), cURL commands, and JavaScript/Python scripts provided across HTTPLens articles and interactive tools are released for free educational and commercial developer use under standard permissive terms (MIT / Public Domain dedication for snippet integration).

3. Disclaimer of Warranties (Diagnostic Tool Disclaimer)

HTTPLens documentation and tools are provided on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied.

Production Safety Recommendation: While all guides are rigorously cross-referenced against authoritative IETF and WHATWG standards, network topologies, firewalls, reverse proxies, and cloud providers vary widely. Developers must always test CORS rules, caching headers, rate limit thresholds, and status code changes in a safe staging or testing environment prior to production deployment.

4. Limitation of Liability

Under no circumstances shall the authors, maintainers, or contributors of HTTPLens be liable for any direct, indirect, incidental, consequential, or exemplary damages—including but not limited to loss of data, service interruption, security vulnerabilities, or infrastructure costs—resulting from the use or inability to use the information and tools provided on this website.

5. Intellectual Property & Standard Citations

All original written technical synthesis, diagrams, and tool interface implementations are the intellectual property of HTTPLens. Protocol definitions, RFC excerpts, and standard specifications cited throughout this site remain the property of the Internet Engineering Task Force (IETF), the World Wide Web Consortium (W3C), and the WHATWG, referenced fairly for technical attribution and educational clarity.

6. External Links & References

HTTPLens provides outbound hyperlinks to official RFC documents, MDN Web Docs, OWASP benchmarks, and cloud documentation for developer convenience. HTTPLens does not control or assume responsibility for external third-party content.

7. Modifications to Terms

We reserve the right to revise these terms as necessary. Continued use of HTTPLens following published updates constitutes acceptance of the modified terms.
