흔히 이렇게 알고 있다
HostAuthorization accepts wildcard glob patterns like '*.example.com' in permitted_hosts to authorize all subdomains.
이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.
컨트랙트
- HostAuthorization treats '*.example.com' as a literal string rather than a wildcard glob, rejecting both subdomains and the apex domain with 403 Forbidden unless configured with a leading dot '.example.com'.
- HostAuthorization with leading dot '.example.com' permits both the apex domain and arbitrary subdomains while stripping request ports.
- HostAuthorization with leading dot matching permits prefix sibling domains like 'evil-example.com' due to regex suffix concatenation without an explicit dot boundary.
- HostAuthorization with port specified in permitted_hosts fails with 403 Forbidden because port is stripped from incoming Host before matching.
- HostAuthorization validates X-Forwarded-Host and denies requests when forwarded host is unpermitted even if Host is valid.
- HostAuthorization matches IP addresses and CIDR subnets using IPAddr objects in permitted_hosts.
