retryableStatusCode
boolean retryableStatusCode(int statusCode) If an exception is not thrown when making a request, this method will be called to see if the client would like to retry the request based on the status code returned. For example, in Cloud Foundry, the router will return a404
when an app is not available. Since HTTP clients do not throw an exception when a404
is returned,retryableStatusCode
allows clients to force a retry.- Parameters:
statusCode
- The HTTP status code.- Returns:
- True if a retry should be attempted; false to just return the response.
