> line-705:defineFilter() doesnot check filter if it exists.we need check if it exists before add it.
> another,No_Cache_Filter added twice when create a HttpServer2 object.I think addDefaultApps()  invoke addNoCacheFilter() is unnecessary.because addNoCacheFilter() has already been invoked by createWebAppContext()  in httpServer2 constructor method.
