trait RetryMiddleware extends AnyRef

Implement retry transparently for a Client as Middleware. For dynamics, this is a bit hard as the server could be busy but returns 500. Otherwise, other 500 errors maybe or maybe not should be retryable. The retry policies herein are based on specific statuses, specific OS likely retryable errors and errors caused potentially by mangled message bodies.

The new dynamics governer limits are in place and these retry policies take them into account via status TooManyRequests:

    Construct middleware with retry strategies which ensure that responses with statuses known to be retryable are retried.

    Construct middleware with retry strategies which ensure that responses with statuses known to be retryable are retried. The retry policy is embedded in the "retry" parameter. Therefore, your effect must be able to express "retry" semantics. "retry" is composed with the output from the Middlware's input Client. Your retry strategy may wish to filter on different types of errors so that not every Throwable causes a retry. makeSomeStatusesErrors is automatically composed.
