public class NonExistingDispatcherServlet
extends GenericServlet
implements OptingServlet

NonExistingDispatcherServlet is a solution to dispatch the sling:nonexisting resource type based on dynamic acceptance. With standard Sling it is only possible to register a single servlet for each HTTP method on the nonexisting resource.

Please note: This is a temporary solution until Sling provides a built-in mechanism for this use case. Not to be used by client implementations!
