      • registerThrowable

        void registerThrowable​(LoadBalancedRetryContext context,

        Called when the execution fails.
        Parameters:
        context - The context for the retry operation.
        throwable - The throwable from the failed execution.

      • 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 a 404 when an app is not available. Since HTTP clients do not throw an exception when a 404 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.
