What is a .headers file?
A .headers text fixture is a plain-text dump of HTTP response headers (CORS, CSP, HSTS, etc.) used for policy and scanner tests.
How to use this file
Use SAMPLE .headers files to test security-header parsers and linters against documented good and misconfigured policies.
How to use this file for testing
“X-XSS-Protection Header — SAMPLE” is a deterministic Novus Examples fixture for API testing. OpenAPI/Swagger specs, GraphQL SDL, JSON Schema, paginated and problem+json error payloads, and webhook samples — for testing API clients, mock servers, contract tests, and schema validators.
Documented properties for this file: HEADERS · 21 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
This is published, SAMPLE-only security material — never a real secret. Point certificate, key, or token parsers at it, test PEM/DER decoding and PKCS handling, and confirm your tooling reads the documented fields; any sample password is printed on this page.
