  4. AbstractWebConsolePlugin.renderContent(HttpServletRequest, HttpServletResponse)
  5. AbstractWebConsolePlugin.endResponse(PrintWriter)

Note: If a resource is sent back for the request only the first step is executed. Otherwise the first step is a null-operation actually and the latter four steps are executed in order.
