resolvedHost property
The expected host present in the Host header of the request, not including the path or scheme (for example, "prefix.example.com"). If no resolvedHost is defined, then no assertions are made about the resolved host for the request.
This can differ from the host provided to the client if the operation
has a member with the endpoint trait.
Server implementations SHOULD ignore discrepancies in paths when comparing the host and resolvedHost properties.
Implementation
final String? resolvedHost;
