Interceptors
============

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. Here's a simple interceptor that logs the outgoing request and the incoming response.

```java
class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Interceptor.Chain chain) throws IOException {
    Request request = chain.request();

    long t1 = System.nanoTime();

	// global Listen system to send S3 API events to registered listeners
	globalHTTPListen = pubsub.New[event.Event, pubsub.Mask](0)

	// global console system to send console logs to
	// registered listeners
	globalConsoleSys *HTTPConsoleLoggerSys

	// All unique drives for this deployment
	globalEndpoints EndpointServerPools
	// All unique nodes for this deployment
	globalNodes []Node

    boolean isAllowGuestFallback ();
