public class NonResourceWebContentInterceptor
extends org.springframework.web.servlet.mvc.WebContentInterceptor

This class is used to control the cache seconds. The default Spring WebContentInterceptor will apply the cacheSeconds and associated variables to everything that goes through Spring MVC. We only want to apply the configured cache settings to requests that go through controllers. For static resources, we will let Spring use its defaults. Additionally, for requests for files that are known bundles, we will cache for a full 10 years, as we are generating unique filenames that will make this acceptable.
