 `resources.Get` and `resources.GetRemote` return `nil` if the resource is not found.
 
+{{< new-in "0.110.0" >}} You can get information about the HTTP Response using `.Data` in the returned `Resource`. This is especially useful for HEAD request without any body. The Data object contains:
+
+StatusCode
+: The HTTP status code, e.g. 200
+Status
+: The HTTP status text, e.g. "200 OK"
+TransferEncoding
+: The transfer encoding, e.g. "chunked"
+ContentLength
+: The content length, e.g. 1234
+ContentType
