Why Check HTTP Headers?
- Verify security headers like HSTS, CSP, and X-Content-Type-Options are correctly configured
- Debug caching policies with Cache-Control and ETag headers
- Validate CORS policies to ensure cross-origin requests behave correctly
- Identify missing or misconfigured headers before they become security vulnerabilities
