Element	Cardinality	Description
httpClientConfig	0..1	Connection pooling, timeout, retry, and proxy settings for outgoing HTTP connections made by this element. When omitted, the router's global `httpClientConfig` applies.
target	0..*	Shadow hosts each incoming request is additionally cloned and sent to in the background, once its body has been read completely. A request whose body could not be read is not shadowed. Responses from the shadow hosts are not returned to the client. A 5xx response is only logged.
