public interface InsertableServlet
extends PipelineableServlet

An InsertableServlet is a PipelineableServlet that knows how to splice itself into an existing servlet pipeline at startup time. This capability is required because it is difficult to reliably use Nucleus configuration files to splice into a pipeline whose configuration cannot be completely determined when the configuration files are written.

An InsertableServlet should explicitly add itself into a pipeline when the service is started, using the the "insertAfterServlet" property to determine its location.

An InsertableServlet may have a nextServlet field; that is, it may be part of a pipeline itself. If so, it should insert itself into the pipeline after the "insertAfterServlet" servlet, and should place that servlet at the end of its own chain of servlets.
