### Handling authentication ([.kt][AuthenticateKotlin], [.java][AuthenticateJava])

OkHttp can automatically retry unauthenticated requests. When a response is `401 Not Authorized`, an `Authenticator` is asked to supply credentials. Implementations should build a new request that includes the missing credentials. If no credentials are available, return null to skip the retry.

                throw new SmbException("Invalid operation for workgroups, servers, or shares");
            }

            if ( !sh.isSameTree(th) ) {
                // trigger requests to resolve the actual target
                exists();
                dest.exists();

                if ( !Objects.equals(getServerWithDfs(), dest.getServerWithDfs()) || !Objects.equals(getShare(), dest.getShare()) ) {

Das ist auch bei den meisten Webanwendungen der Fall.

Viele, viele Benutzer, aber Ihr Server wartet 🕙 darauf, dass deren nicht so gute Internetverbindungen die Requests übermitteln.

Und dann warten 🕙, bis die Responses zurückkommen.

Dieses „Warten“ 🕙 wird in Mikrosekunden gemessen, aber zusammenfassend lässt sich sagen, dass am Ende eine Menge gewartet wird.

	go pool.resyncer.PersistToDisk(ctx, o)
	go pool.processMRF()
	go pool.persistMRF()
	return pool
}

// AddMRFWorker adds a pending/failed replication worker to handle requests that could not be queued
// to the other workers
func (p *ReplicationPool) AddMRFWorker() {
	for {
		select {
		case <-p.ctx.Done():
			return
		case oi, ok := <-p.mrfReplicaCh:
			if !ok {

// are responsible for serializing and deserializing the objects that contain
// their internal state.
// Once a ControllerRevision has been successfully created, it can not be updated.
// The API Server will fail validation of all requests that attempt to mutate
// the Data field. ControllerRevisions may, however, be deleted. Note that, due to its use by both
// the DaemonSet and StatefulSet controllers for update and rollback, this object is beta. However,

This is the case for most of the web applications.

Many, many users, but your server is waiting 🕙 for their not-so-good connection to send their requests.

And then waiting 🕙 again for the responses to come back.

This "waiting" 🕙 is measured in microseconds, but still, summing it all, it's a lot of waiting in the end.
