Ce que l'on suppose souvent
Rack::Protection::HostAuthorization permits requests whose Host header matches a permitted domain even when an untrusted X-Forwarded-Host header is present.
L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.
Contrat
- `Rack::Protection::HostAuthorization` rejects requests with HTTP 403 when `X-Forwarded-Host` contains an unpermitted authority even if the direct `Host` header matches `permitted_hosts`.
- `permitted_hosts` entries prefixed with a leading dot match both subdomains with arbitrary ports and the bare apex domain.
- `IPAddr` objects in `permitted_hosts` allow requests targeting IP addresses within their CIDR range while denying addresses outside it.
