- Interface Summary
  Interface | Description
  --- | ---
  JavaScriptStackAssembler | Assembles the individual assets of a `JavaScriptStack` into a single resource; this is needed to generate a checksum for the aggregated assets, and also to service the aggregated stack content.
  ResourceChangeTracker | Tracks resources (at least, resources that can change because they are on the file system) and acts as an `UpdateListener` to check for changes and notify its listeners.

  ClasspathAssetRequestHandler | A handler for asset requests for classpath assets (within a specific folder).
  CompressedStreamableResource | GZip compressed representation of a `StreamableResource`.

  CSSURLRewriter | Rewrites the `url()` attributes inside a CSS (MIME type "text/css")) resource.
  DelegatingSRS | Base class for `StreamableResourceSource` implementations.
  JavaScriptStackAssemblerImpl |
  JavaScriptStackMinimizeDisabler | Attempts to match resources against a `JavaScriptStack`, and possibly disabled minimization based on the stack.
  MasterResourceMinimizer | Implementation that delegates, via its configuration, to a real implementation based on the content type of the resource.
  ResourceChangeTrackerImpl |
  SRSCachingInterceptor | An interceptor for the `StreamableResourceSource` service that handles caching of content.
  SRSCompressedCachingInterceptor | Specialization of `SRSCachingInterceptor` that only attempts to cache compressed resources.
  SRSCompressingInterceptor |
  SRSMinimizingInterceptor | Loops the result through the `ResourceMinimizer` service.
